Senile at 40???

Today I took Autumn and a friend to a paint ball battle to meet up with some of her other friends (it was the b'day of one of the boys). His mom was there and she just talked and talked to me. Since it was so far from our house, she offered to bring Autumn and her friend home. I thought.."She sure is a nice lady." We left and went to get ice cream while they played. We came back about 30 min before it was over and I just talked and talked to this woman and her husband. Then she started talking about people I went to school with. I said, "Did you go to Dora?" She looked at me kind of crazy and said,"yes". I said, "Now, what did you say your name was?" She looked at me even crazier and said, "Nancy, Nancy ******" I was so embarassed... we grew up together and went to school together from 1st grade to 12th. We were in Girl Scouts together and I even spent the night at her house. I guess she thinks I am so crazy.
