When someone invites you to a party, is there a certain way you are expected to behave?
I was invited to 5 parties by 5 different friends, and the parties were all at different times by different friends and had no correlation with each other. I did not talk at all to the host or the host's family or friends at the party, and I was never invited again. I also didn't hear much from them either. The parties happened 10 or so years ago, and I know the hosts have done a lot of parties since then.
