<human>: Can you succinctly summarize the text in 1-3 sentences?

TIFU by borrowing earphones when usually i do not do that. I'm always uncomfortable with that because i feel like i'm swapping ear wax with them. Today i did something different and that's why i  screwed up. 

I would like to first and foremost say that i am a person of good hygiene and regularly clean my ears.....except for today and yesterday.

Here we go....Today a friend of mine offered me their headphones in order to show me a video. The usual deal. This time i accepted, which is quite unlike me. When i returned the headphones my eyes immediately focused upon a black speck which was now upon them. My heart had stopped. She hadn't noticed the speck as of yet, but it was only a matter of time. When the time came she simply wiped it off. I felt so embarrassed. Then she proceeded to use only one of the earbuds the entire time. I want to cry.
<bot>: I borrowed headphones, left a "present" and now i'm really embarrassed because they (obviously) would not continue using that earbud.
