Depends... i mean if someone is always negative then i will, of course, try to avoid them. However, if that's not possible i will attempt to move conversation into a more positive light... normally i can. Not too many miserable people out there that i haven't been able to crack. Honestly, it's the only skill i do have which is turning negatives to positives. It a drain, yes, however i think if you can find some understanding as to why a person maybe negative, then you can also find the opposite to carry them out of it.
