Mum's birthday

Today was my mother's birthday.
My mother just celebrated her 55th birthday.
Do you know how that makes me feel?
I reckon if my mum is getting old that can only mean one thing....am getting older too.
The weirdest thing is i dont even know if she minds the aging but for me it's another constant reminder of how the years are passing by.
I guess i could worry for both me and her.
