Oh I know!! I can't imagine dating someone that much older - not in my 20s, anyway. Plus, it wouldn't last long, because my father would kill him.
No offence to anyone out there but if a 24 year old DOES date a 40 year old, either she's a gold digger or has some serious father-daughter issues to work out.
Oh and don't forget, she'll have a 26 year old on the side for her fun.
