It's different from my daily, regular, forgetfulness.
On those special days, I go to work, I have a normal day, I laugh with coworkers (I'm super funny), I come home for dinner with my husband, and life is good.
It's not until I go upstairs and hop in the shower that it happens. I see myself in the mirror - I only have one boob.
I know that I should know by now, but I don't. The flat side of my chest - the horizontal scar - they remind me.
