meeting people

so i've met these people. they're a couple. they seem to be your average okay people.

actually, i take that back. she's okay people. he's smarmy, obnoxious, and opinioniated without justification. and he has horrible taste in music.

now what do i do? there's no avoiding them, so must i be friends with them? would that be the right thing to do? or would that be disingenuous?
