2 years ago, in a hot summer, i had a fly stay the whole day with me. When i noticed, i first shushed it away and it kept landing on the same spot. Since it wasn't really bothering me, i kept the fly in my view and it was absolutely always landing and staying very close to me, but never touched me.

It followed me through the whole house, wherever, bathroom, kitchen living room - it was always just a few inches away from me.

I even started to be careful, not to sit on it ... Like this would ever happen, as fast as they are.

Anyway, it was strange and wholesome at the same time. Was gone the next day, i really missed the little fella.

Edit: though, they live longer, or? Afaik, the flies that only live 24 hours are mayflies.

I'm sure my fly was a common house fly. Must have gotten bored with me, after a day.

Edit 2:

Must have gotten bored with me, after ~~a day~~ i took a shower.

TheSlad, thanks for reminding me
