Mehehe, I just thought about this for a second and I have a checklist but it's pretty small:
A girl who is,
~Humorous and witty in a good way, I mean. But making fun of others or using dirty jokes, ye shall get out, now
~Happy go lucky/Jolly
~Smart/Clever
~Neat/Presentable/Knows proper grooming
~Adventurous
~Share some of my interests at the least
But honestly, it all comes down to personality... a very caring girl not to just one to some person but to everyone is a big big yes.
And, I ain't pretty much looking for anything much when it comes to the physical aspects.
