You’re Welcome

http://lifeprint.com/asl101/pages-signs/w/welcome.htm

The sign WELCOME has several meanings and interpretations.  For example, it also means: “hire” and “invite.”

My recommendation is that you use this sign to mean things like:

"Welcome, come on into my home."
"I hired him."
"I invited her.

I recommend that you do NOT use this sign as a response to “Thank you.”

So, what should you do if someone tells you “thank you?”

I recommend that you reply with one of these:

TRUE/SURE
FINE
NOTHING-TO-IT
HAPPY HELP-you
THUMB-UP
ANY TIME
NO PROBLEM
