I understand a lot more..

I talked to my siblings about my problems...

My brother told me that
1)Some friends you can talk to them, but is just that can't talk much..
2)Everyone's interest are different..
*So, some ppl may like you but some ppl may hate you..
3)A topic that we like, ppl may not like..

My sister told me that

1) Some topics is just not suitable to talk to certain ppl.. It's like the feeling is not right..

After they told me, I understand a lot more better !
