I used to be really shy, I used the blur trick several times and it works!!!

I meant to like

I didnt know about the blur trick. I used to just focus on their mouths or chins ^^" I still do that sometimes to strangers/acquaintances. I might try that blur trick next time tho.

I used to do it in order to avoid some people or avoid to look directly a person that was making me angry, but it only works if you have some distance, some people can detect you are not looking them directly.

I never used it to avoid looking a hot guy though.

Note: I have scary eyes when I'm angry, so blur the face of someone that is making angry helped a lot to avoid scary eyes.

Also, when I was young, people faces scared me, I was really shy and it scared me to see an angry face, mocking face (I was bullied a lot as a kid), etc...
