is my problem or yours problem?

i realize that i don't really like to lend things to people. the people that i means was my classmates or course mates. this is because i very worry they will copy my idea. i don't like it!!!!!! but i couldn't show it to them!! oh gosh!! we attending the same class the same lecture. how come i can copy so much of information and u cant? i really don't know what are u doing while she teaching lo... then very easy for u to open your mouth and say please lend me.. could u lend me? smile to me so nicely.. oh my!!!!!!!!!! honestly, i wanna to say NO but it seem like i could not say this word! is it because i am stupid or very nice to be used by other? or i am too kind to them?

i didn't means that i don't lend things to people but i will just choose certain people can lend and certain can not.. that's me

so this was my problem or yours problem????
