You have examples
of other's
being polite to spare your feelings

that's about it
and I can tell
since you're not funny

No I've definitely made people laugh plenty. I'm for sure funny irl. Even real irl GIRLS find me funny smiles, I know you'll find that hard to believe but it's the case.

it's easy to figure out
how easy it is
to fake a laugh
gpt
I'm aware. I fake laugh all the time when I'm around those less funny than myself. But, I make people real laugh (at my jokes/comments, and not me) and I have incontrovertible evidence of it. 

But everyone has a different sense of humour of course.
