Is it normal to snap your fingers when you're trying to remember something?

Not normal, get a lobotomy.

Annoying..Please, only do that when you're alone...

I do that too and many i know do it so i guess you're fine:)

Things like that help us remember things because of operant conditioning
Totally normal and useful af

I tap my fingers together softly.

Every body has a little trate my dad used make a clicking noise when he was trying to remember something

It's just a little quirk.

Course it is, everyone does it xD
