What do i do in an akward situation?

Ok, so i was in an extremely akward situation:

Person: Misskitty is deathnote your brother?
Me: No
Deathnote: I wish yes idk
Me: Not sure how to respond to that
Deathnote: I see your back x
Me: WTF

What do i do in an akward situation like this?

 

Well, my friend and I discussed awkward situations and, through a serious of experiments, we have come up with the greatest solution. If there is ever and awkward silence or just conversation in general, say the word "false." That's it, just "false." They will be very confused, and in that time you must just run away from them until they can't see you. Trust me, I'm a professional.

 

Ignore him, lmao.
