Friends
Everyone needs friends. Us humans are social pack animals, and we can't live without companionship. So, to do this, a lot of the time we go out somewhere to have fun, maybe for some kind of event. That's what I like doing.
This is a couple years back, around Christmas time. There was some sort of festival/event thing going on where I was for a couple days. I happened to have some friends I knew from a while back in that area, so I figured I'd use the three or so days to catch up with some of them. They were some great friends, after all. So, I made a whole thing of telling them where I was and what we could do and all that. They read all my messages and we made arrangements, and I figured that was the end of it.
So the day of the thing rolls around, no answer in the morning. "Alright, they're probably late or something. Perfectly normal, why would I expect anything? Cue my growing suspicion as the day continues to go past - lunchtime and still nothing. Sure, maybe they're off getting lunch without me. Not that weird, I guess.
