When did I get so old?

Once upon a time, I used to sleep until 11am on a regular basis on my days off from work and school. The other people who lived near Sean and I in family housing used to laugh when my alarm would go off to wake me up at around the time they were getting ready to feed their kids lunch! These are the same people who would get angry when Sean and I had parties into the late hours of the night/morning. Well, I never really understood them...until last night. I was laying in bed and it was raining really hard and I was having trouble falling asleep...and, all I could think about was I had to get to sleep because the kids would wake up early and I needed to have a good night's sleep before that... And then, I got the giggles...I finally understood...I was finally OLD!
