I used to think it was me and take it personally. I will say more often than not a so-called friend will cancel plans the day before or the day of. Sometimes they will cancel less than 10 minutes before we are to meet to go somewhere. I organized a birthday party a few years ago and invited 15 people. They all said yes but then only two showed up. I was calling and texting and never got a reply from the other 13. No one knew one another so it was not as though they conspired together to stand me up.
I hear this is common these days and a lot of people complain about so-called friends canceling, flaking, and not showing up when they said they would. My parents were born in the late 1970s and said it was almost unheard of for people you knew to do that. Sure it happened but not as much as it does today. I saw an episode of The Simpsons and Homer said to Bart that his own generation actually shows up for things they say they will unlike the generation Bart is in. That means it is not a niche thing. Millions of people are noticing it.
Does anyone have any idea why flaking and standing people up became normalized?
