PEER PRESSURE

why does peer pressure have to be a thing (exist)
why i ask this is bc we all know about it and hate it
except for the people who use it (bullies)
it's becoming harder to see thru the repeated blur of hatred and jealously
we expect it bc we have to
i myself do a double take when i am around someone who wants to be my friend
it hurts to know that. it hurts to expect the worst of a human
but we have to keep that shield up for we are done with being used and hurt

i guess you can say we use peer pressure to beat it
is that wrong or?...
