DUH

My 3 year old daughter just duh'd me! We recently rearranged our living room and I forgot there was a trash can right next to where I was sitting so I told Keira to throw something away and she said no so I started to get on her and she pointed to the trash can right next to me. I said I forgot it was there and she says "Duh, Daddy put it there". She's growing p so fast but I'm not so sure that's a good thing!
