Jill's 7 year old feet

Jill turned 7 on August 15th. In the morning she asked Michelle what time she was born and Michelle told her 11:43 a.m. Through the course of the morning, Jill and Michelle got distracted and didn't pay attention to the time. Later in the day Jill was lying on the bed watching t.v. and asked, "Mom, what time is it?". Michelle told her the time (it was well after the "birth time") and said oops - we missed 11:43. Jill looked down at feet and said "Yep, I knew it. They're bigger. I now have 7 year old feet".
