just because your friend is bisexual, gay, lesbian, etc. does not mean they like you.
it’s called personality traits, not gender traits. if a person is bisexual, gay, or lesbian, it does not mean they will at one point be attracted to you. it’s not as if they are going to like you just because you are a boy or girl. treat them as humans, not as something you should be afraid of. the sooner you understand this, the better off you’ll be.
