Out of Topic but how do I friend zone a guy?
Usimov [2.4K]
If it's getting annoying or is in any way inappropriate, cut it off now. However, if he is not completely mean, wait. You don't want to be unkind. Funniest thing to do would be to say "You're like a brother to me," But that would be mean and awkward, so it's best to just wait it out...

Answer:

10 Smart Ways to Get Your Crush Notice You

SEPTEMBER 30, 2021 BY CYRIL ABELLO 102 COMMENTS

start of friendship

Has someone caught your eyes lately? Do you get insomnia thinking about that person all night and spend the whole day daydreaming about your first date? You probably can’t focus at school or work because that person keeps on popping up in your mind. The problem is, you’re not sure if all these distractions are worth it since that person may not feel the same towards you.

Falling for someone could cause you headaches—not just heartaches—especially if your crush doesn’t even know you exist. You feel butterflies in your stomach whenever your paths cross, but s/he doesn’t even throw you a single glance. So frustrating and disheartening, right?

Instead of waiting for nothing, why not try to find out if there could be a chance for your crush to like you. However, I’m not saying you confess your feelings or make it obvious to that person because it might cause him/her to repel you instead. Hmm.. maybe you could help him/her a bit to notice you.
