After-Effects of a Birthday!!

What exactly is the concept behind the basic expectations on the after-effects of a birthday.

1. You are a year older so act mature
2. The stupid jokes have to stop now
3. Its time to manage the bank balance more efficiently
4. Make sure you dont looke hyper excited about the presents
5. The toy train and pink barbie on the list get changed to diamond rings and massage chairs
6. Go dye shopping to hide the latest addition of white hair on the new haircut
7. The floral shirt and purple glasses are not cool anymore
8. Party planners get replaced with financial planners

Hmmmm on second thoughts maybe the making of lists and the blah blah blah have to stop as well!!!!!!!!!!!!!!
