Why do people say Hi but then don't say anything else?

because alot of people expect the other person to start a conversation.

I think some people just don't think past that point so when someone actually responds they're like..WHA 😧 errrmm lol

They're just being polite... forced conversations aren't that great.

Do you mean on here or out there?

It can be frustrating.

Nobody ever says just 'hi' to me. xD

It happens a lot, not sure why

Weirdos. 🤷‍♂️

Hi

I know then two weeks later they say h again
