It is tough to get to know one another.

No. That means you're new friends and they thought it would look like "Gimme a gift" if they told you it's their birthday.

I mean I honestly don't know. If I had a clue how people's minds work I probably wouldn't be on this website.

That’s so childish...lolz

Nah, they probably felt awkward telling you, nothing more. Just wish them a belated birthday and stop overthinking.

No. I'm like that too. It means they didn't want to burden you.

Idk. For me I'm not big on birthdays so I don't really tell anyone about mine

I never make anything out of my birthday and I would feel odd saying to a friend “today is my birthday” because I wouldn’t want them to think I’m expecting them to do something for me

No that doesn't mean you're not friends. I keep my birthday hush/hush. I always hated celebrating it.

My birthday is Friday, some people will do the "Happy Belated" thing. It's all good.
