There's a really easy way to tell when you've achieved that certain level of maturity...
It's not when 20-somethings start calling you ma'am.
It's not when you start getting grey hairs. Nor yet when you start wondering when hell skirts got so short. Not even when you think that a night of dancing and vodka & Red Bulls is just too much work.
Its not when you look at a cute guy and your first thought is not 'rowr!' but 'good lord, comb your hair', not when you slam on your brakes and your arm insinctively flies out to protect the passenger, not even when your idea of being hot has more to do with flashes...
None of it.
What DOES tell you that you are now of THAT age, ready to ake your matronly place in the Halls of Maturity?
Its when your MOTHER now views you as peer and forwards raunchy sex jokes to you, to your dad's utter horror. And THEN calls to ask if you got it.
Please pass the Clorox and the qtips, I have some grey matter to santitize.
