<human>: Last night after I left a party at my girlfriend's house my girlfriend, two of my friends (both guys), and a girl one of my friends hooked up with that night smoked together. During this smoke sesh my girlfriend blew smoke in my friends face as a joke and I guess he got the wrong idea because he shotgunned with her shortly after. 

For those unfamiliar with the term it's when you blow smoke directly into someone's mouth, usually with a kiss but not in this case. To do this, one needs to be practically centimeters away from kissing.

Now I didn't hear this from other people she brought it up and told me but I don't think she gets how weird it is that they did that, I mean she understands that it's strange but I don't think she sees how I wouldn't be comfortable with it. 

I don't know how many times this occurred during the smoke sesh but i'm fairly pissed right now. After she told me I didn't really freak out but I did make it very clear I find it weird. I guess all i'm trying to say is that I don't know if this is as shady as I think it is. I mean I know she loves me and does not find him attractive but I can't say that i'm totally cool with it.

Can you give me a shortened version of the text?
