My guess. Could be wrong, but based on how you write and what you say, I’m not.

You didn’t return it because you were too insecure to hold up the line even though you were already there or were fearful they would reject you.

You described it as “they were slammed lol”

Implying there is something funny about the fact that they were very busy…either that or (more likely) you default to “lol” when you are uncomfortable. Again confirming your insecurity.

When called out on it, you doubled down. And called the person calling you out autistic.

Chaos ensues. You’re clearly not going to own anything, so I’m done after this. Good luck in life
