"I am well, and you?"
"Merçi!"
pleasure
When some says "wassup" you would reply as if someone asked you " what's up."
and the rest of the day to you
A smile and a heartfelt "Thank you".
You could say, "I'll try."
If someone says sup in chat then the reply is usually nuttin. Sup is short for whats up
We use "How do you do?" when we meet someone 1st time. It's a formal greeting and a reply is not necessary. It's used as "Namaste". the reply of 'Namaste' is 'Namaste'. then reply of 'How do you do?' will also be same (How do you do?)
The most appropriate reply would be "Thank you."
You answer with xoxo back. xoxo are kisses i think .
go to the video where someone has commented, and under their comment there is a button that says "reply" :)
You should reply "and the balance of the day to you."
