Do you have a middle name?
Can you use that?
Is your full name
Theresa? Are you looking for something similar to your real name?
No, it is easy to spell and pronounce. But I dislike it. I think it sounds incredibly harsh and somewhat dated even though it was never popular. I can't think of any jokes. I have known two Tessas one should be mid-20s now, one early 30s.
I much prefer
Tess which I find softer and prettier.
