Life is just too short. It really is. A large chunk of your life is spent as a kid with not a lot of control over your universe, well, not really. Your parents may give in to you, but, in the end, it will come back to bite you in the ass when you realize that isn't how life works, which brings us to the next chunk of your life. I like to call this the "I know absolutely everything, yet I am clueless what I want to do with my life" phase.
This phase is my freaking favorite to watch from the sidelines. Mind you, I was a total freaking idiot with no clue as to what the heck I was doing, but you couldn't tell me that because, yes, I knew freaking everything. And, of course my mother was right. She just was, and so is yours. Suck it up, Princess, because you will figure out one day that she really is right. And she is right because when she was your age, she was right there, messing up her own life with no clue. It is a vicious circle of life that nobody really escapes from (cue Lion King Music). The Gods have a sense of humor. Just freaking deal with it.
There is also this weird brief phase after all that, sort of a post apocalyptic lull, where, if you are lucky, you figure shit out and get to listen to your mother say "I told you so" a whole lot. Just suck it up and let her do it. She screamed bloody murder while pushing you out her vagina so she has earned a bit of your time, and some serious gloating points. So, whether she is standing right there with the bail money in hand, taking a moment to take advantage of your undivided, jail-cell-occupying attention, or stealthily waiting like some Karmic Ninja, stockpiling numerous "I-told-you-so's" just so she can spring them on you all at once while you are driving her to the doctors or to the store for toilet paper. You just need to shut up, pull your big girl panties up and just take it.
Because, there is something important that you need to understand. Moms aren't forever. I am fortunate enough to have my mom still, who really likes to say "I told you so" a whole lot. But, there are people out there without moms, who wish there mom was still there to bust their balls about something epically stupid they did. It is one thing to do something epically stupid and then have the torture of listening to your mother tell you just how epically stupid it was, but it is monumentally worse to do something epically stupid, and be met with a momless silence.
So, this Mother's day, don't just give your mom a card, or flowers, or a car (well, you can buy her a car, that would be ok), give her time, that wonderful, golden, fleeting gift of your time so she can tell you just how completely you have wasted your life and you could have done something so much more awesome than becoming a doctor who cures cancer in kids or a supreme court justice (you know you could have done better, slacker). Listen to it. Take it in with all the love and adoration you can muster, and even thank her for showing you that being a rich and famous writer is such a dead end job, you are going to find something much more worthy next week. This is what she wants because, to her, time equals love. Time is the real currency of the mothers of adult children. It is always too late when the adult child realizes that it goes both ways, that time with her is their currency too.
And, if your mother is no longer with you (and I am truly sorry for your loss), take a moment and think of every time she told you, "I told you so," and send her a loving thank you from your heart. She will hear you because she is still watching, still tallying up all those epic mistakes you continue to make with your life, even finding little ways to smack you in the back of the head when you cross too far over that line. And she is stockpiling some good material for when you meet again, in the great beyond, so she can take your hand, kiss your cheek, and say... "I told you so."
