Am i a weird people?

today dunno y
suddenly dislike(teacher said HATE is a cruel word, so i use dislike)someone since the morning
i really dunno y the reason i dislike him/her
his/her behaviour...?? attitude..??
i'm wondering~~~~~~~~
Y Y Y Y Y ???????????
and 1 more thing
i don't like to hide my feeling
what my heart felt usually will express on my face
is this good or bad...?? or both...??
maybe he/she could feel the difference with the way i treat him/her
it's obviously
actually, if i'm anger or " beh song"
i will act rude on that person
so
please don't force me to do that
i don't know how to be normal and act like nothing in front of friends
it will be so obvious

the weird is
i will loss this "dislike feeling" very quickly
maybe another day or after fews hour i will be nothing ad
我的情绪来得快也去的也快
once he/she do something i couldn't expect or hurt me
even his/her behaviour
maybe in others opinion
they feel that's just a small matter
but the fact is
i will dislike he/she again
haizzzzzzzzzzzz
am i a weird people...??
