"Are we old yet?"

I forwarded an e-mail to my dad recently about some jokes regarding "Are we old yet?".
I didn't expect any reply cos it was just a forwarded email with jokes.
His unexpected reply was:
"no not yet. old is when u stop working"

so, i paused and think... I felt like a guilty mother again going to work this morning, leaving my son crying in front of my car! When the time comes for me to stop working, then I will instead appreciate the time to work!

Anyway, I am still glad that my parents are working! I just hope my son will grow up soon to stop crying every morning when I leave to work.
