Input: Text: my fu starts about a week ago. i was babysitting my sister-in-laws kids with my wife. they are a boy and girl, ages 2 and 5 respectively. shortly before bed time they asked if i could play hide and seek with them. this is kind of a tradition with us and we do it every time we watch them, they enjoy it because i make it really easy for them. having my feet stick out from under a blanket for example. 

anyway i chose to hide in the bathroom right behind the door. it was my nephews turn to find everyone. he had found everyone else already and i could hear him getting closer to my hiding spot. and this is where my fu happens. i get the brilliant idea to say boo right when he comes around the door. he sticks his head around the door and we make eye contact. i yell the loudest boo i ever had he screams and then starts giggling that giggle little kids do when they've just seen the funniest thing ever.  alls good right? nope.

fast forward about a week and i get a call from my sister in law asking me why her two year old, who she has been struggling with potty training for a while now, is suddenly afraid of bathrooms. i tell her what happened and that i thought everything was okay. she starts yelling at me about being irresponsible etc. etc. then she calls my wife and chews her out. now my wife is mad because of my poor judgement. im hoping everything will be ok but i think i should just lay low from that side of the family for a while.
