A Case of Forgotten Cuteness...

I've been babysitting my granddaughter for years now, and I have a confession.... Whenever she asks me to tell her how cute she is, I sometimes forget the last time she did it. It's not that I don't think she's adorable, she certainly is!, but I get so caught up in my own thoughts and activities that before I know it, she's reminding me again... Is this normal for a grandparent or am I slipping? What do you all think?
