Im not 25 til next month and I can relate to most of those...
You know your over 30 when....
You see something usefull at a bargain price, and buy a few because "they will make good Xmas presents"
You suddenly realise, while telling your kids what will happen if they dont tidy their room...that you have somehow turned into your Dad "...coz if I do it you'll have nothing in there!!"
You, examine two similar products very closely, because the dearer one, "is a bit heavier, so its gonna be better quality"
Your kids are watching an advert for some whimsical toy, when before they can say "I would like that..." you say " Dont even think about it! Youv'e got enough Doll's, and all they do is end up naked in the bath!!!"
