Your welcome is used after you are thanked by someone and there is no after speech after it.
You should say NOTHING AT ALL and change the topic
I'm good. how are you doing?
Say it back to them. It's a greeting as in what's going on.
You should say "Thank you" when someone says this to you.
You should reply "and the balance of the day to you."
You say Nothing, Im blind, and watch them run away.
When someone says congratulations to you, or when someone congratulates you, say, "Thank you".
if someone says your funny just say lol i know. lol get you out of everything.
The same thing you say when someone says "you're welcome" - nothing.
Just say, Oh. You're ugly. You can't change that. I can go on a diet.
It is called sarcasm when someone says the opposite of what you say in a mocking or ironic way.
