1 they are mad at you
it means he isnt interested depending on what type of laugh you are talking about
talking with a friend
she loves me :p
They are talking about you.
Your friend (in a respect tone) His/her female friend (if talking about other person)
It means she's smiling while she's talking, probably nothing more.
It could be, I've had some of both, yes and no. It could mean that your 'someone that hates you' is saying something bad about you, but your friend could be just listening to that person, or, if your friend agrees that whatever bad the other person is talking about you is right, then your 'friend' is probably not really your friend. You should try talking to your friend about it.
I miss you, friend (when talking to a female)
It might mean he likes you or in some cases your fat
Dont worry about it just because you are in a relationship dosnt mean that she isnt aloud to talk to guy's anymore!(Imagine how miserable she would be! I would) He is probably just a friend of hers! If you are this worried then you obviously dont have much confidence in your realtionship she can handle herself just chill out man;)
Talking is the gerund.
bad isnt the word my friend...
