Well, that sucks, man. Pretty harsh. Here's my advice. You have a few options.

A) Work on your stoned social skills. In your case, you need to work on the 'annoying' aspect, haha. Just make sure you don't intentionally act stupid. Just "go with the flow". [/CLICHE]

B) Start buying weed of your own so you can smoke by yourself and do whatever you want. There's nothin' wrong with that.

C) Both A and B.
