What do you think happens when a person gives you best answer then gives it to someone else?

"Oh, that's funny" *gives best answer*
"Oh, that's funnier" *switches best answer*

I used to think that was accidental until I noticed one person give and take BA 4 different times on one post.
And then I noticed a few others doing it.

It's no accident, they're just nuts LOL

An Indian giver I don’t think that’s politically correct anymore LOL

I'm still surprised I get any best answers.

I feel stupid if I already said thx for BA

Change of heart or they are the new best answer.

Not cool
