If you like each other<br />
what they like to do <br />
where they like to eat<br />
at least one of their freinds<br />
......... the basics
I always always always ask if they are animal lovers. If they aren't, I die a little inside, but as long as they don't outright dislike animals, I still might date them.
If they like oral as much as you like to give/receive
Their name. ;)
Whether or not they are single.
if your both feeling the same thing very important or else you can get very hurt
Whether or not they are gay and hooking up with you for a bet
one month is not long enough to know that he/she is your significant other...
