I thought someone was waving at me but they were waving at someone else. Isn't that embarrassing?

Don't wave at people. Just smile and say hi. That way, if they aren't talking to you and you simply smiled and said hi, you just look friendly instead of "dumb'' for waving.

Super awkward, pretend you were totally trying to run your fingers either through your hair or over your head, that's the best I've got lol.

Oh ma Gosh!! So much I once turned back thought they called my name.. like Sam Pam sounds similar

Did you wave back?
