Just need to vent

Yesterday we had my daughter's birthday party. 20 kids (some siblings and parents not counted rsvped. Mind you about 15 people didn't 😒.. Anyways the day if the party only 8 showed! When I texted to find out what happened each had a major emergency! One had pictures posted on fb of that days activities !!! One I actual know wasn't blowing smoke up my ass and I completely understand not messaging me but honestly I had tons of food and spent tons of money because I thought there was going to be 20 kids!! So done with parties and inviting everyone to be nice! Yes I know its summer but if you say you will come or at least respond and say you can't ! Is that honestly asking too much!! Sometimes living in the south sucks😔
