Kill it and hang it's corpse in the window as a warning to other wasps.

I trapped it and let it loose outside.

I made a deal with it: for it's life, it protects the yard from mosquitoes.

I think I interpreted its antenna waggling as a yes, but I'm not sure which species it is, so it might have been telling me that it will send it's children after my scrotum.

I think it's a 50:50 chance, either or.
