Why should i say yes even i want to say no?

   today i want to about something not formal or too formal. i just think about it when i sit alone.
   seriously i don't think i'm nice person to anyone but some people said that i'm too nice to say yes.
   it mean i will do and follow anyone need help or need me to help them.when i think about it, i realised
   i'm too be nice to them even i shouldn't.what i want to say is everyone have their own reason why
   they say or do that.actually in my heart i really hope i can say no.but when i think about people i loved,
   i don't regret i say yes because it will make them happy.but i actually say no sometimes because i 
   think about myself too and then i'll regret.
   what i want to highlight is everyone can say yes or no and they can think about them or anyone else.
   in other words, say yes or no can give impact to us and other people.
   you don't need to why you can or can't do that. just what you say or what you do can showed how
   many you love that person.
   i need to stop here or maybe i need a tissue to wipe my tears......
