As I have already said.....the game will be over by the time the party starts.Once again, get the app and watch. It's not inconsiderate, it's the right thing to do.
If the hosts have good food and lots of free booze then yes, more people want to be there. Otherwise they're faking it to not be rude.
And this is a small get together for a one year old. What kind of moron is going to have booze?
Good grief, there are a lot of selfish, self-absorbed people in this world.
