Wah, you are so nice! I will never treat my 99 like this. In all celebrations, my C6 and I will just spend at most 1.5 hour with her for lunch or dinner, then will 'peed' ga la. Maybe my 99 is 42 years older than me and C6, we cannot wait for her walking slowly la.
My C6 will give her $ + lunch in birthdays, which I think is enough la.
