you should say im doing fine* how about you *only if you are doing fine
Reply what are you doing now or a simple "sup"
If someone says they're disappointed in you, you must clarify. You must give them proper reasoning of your doing.
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
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.
it doesn't really mean "what's up" people use it to say what are you doing or how have you been but mostly what are you doing
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.
