doesn't have to be anything big, but makes you said "why did I do that?"
For me it was cutting my hair in December...had been trying to grow it long forever (it gets real thing and straggly when real long) and I had one of those "if i dont do something Im gonna shave my head days" and I went and cut like 6 inches off
And I so regret it now
Wishing every day to wake up with it long again...lol
what is the last duh thing you did?
