how do आप react to someone who just can't stop babbling?

I babble a lot, especially when I've had caffeine.
That's nothing compared to my fiance, though. Give him caffeine and he'll shoot through 50 topics in 6 minutes.
Usually I just pretend to listen
THOUGH SOMETIMES I HAVE TO BE LIKE
STAHP PLZ

द्वारा babbling back.

Depends on who it is.
My friend (Yes, I have one of those) will babble on about something interesting, and I want to say something about it, then she switches the topic...I listen for 7 minutes, then when a pause comes...I say "Hey, remember 5 conversations back when आप said...."
It's unacceptable to blab when the other person is clearly listening to music.
I've कहा too much. I'll go.

Someone I know: I'll nod my head every so often while zoning out. If it gets to the point where it's just too much then I'll just make a joke out of it.

Someone I don't know: I'll apologise and excuse myself saying I need to be somewhere. I can't handle babbling from strangers :v

Lol, I'm the one who can't stop babbling! :P

Ignroe them या babble back at a higher degree. XD I might walk away but I might challenge them if they are my friend XD

Sometimes I pretend to listen and sometimes I babble back!

It Really Depends.If They Are Talking About A Subject In Which I'm Interested At I'm Going To Listen.If They Are Not I Usually Pretend To Listen While I'm लॉस्ट In Thought !!!!
