Yeah, the OP is a very immature mindset that I see repeated often. People need to realize that they're not the main characters in others' lives. It's not embarrassing to say, "Hey I heard you were having a party on Saturday, can I join?" If you think it is, the problem is you.

Don't make it awkward for people by putting them in the spot. Maybe they are hanging out with their close friends and you're just not a part of that circle. A lot of people can't really say no when you just up and ask them for an invite.
