Superficial friends

so i've got this friend (whom i met in secondary 3, started officially WA each other in sec 4 i think and then we stopped contacting each other for a while) who suddenly started chatting with me again. So i though, well that's pretty nice of him. (i mean its always good to maintain/build friendships right?) so i happily replied thinking that he contacted me purely just to catch up on what we're doing and stuff...

THEN the moment when he sent his message about borrowing my chinese materials (for his upcoming exams) i was like AH HA THERE YOU GO. don't get me wrong. I wasn't unwilling to lend it to him, in fact i felt to great to be of a help to someone who needs it. But asking about borrowing my stuff ON THE DAY you decided to began contacting me again. is a little.... hmm... i have no idea how to put it but it just made me felt like: So you contacted me just for your selfish needs. ok can. i shall be a kind soul.

 NORMAL CHAT CAME BACK ONLY UNTIL ONE FINE DAY WHEN HIS EXAMS ENDED.

fortunately, he thanked me for lending him my notes. he asked if his sis could borrow it for her exams, and 'ok' i replied. but you do know that my sis is taking the same chinese exams right? (i told you she is sec 3 too -.-) yes, my sis you not have referred to it. BUT you should have asked if she needed it (it's called being polite *uhum*)

ON THE DAY BEFORE HIS OP EXAM (for project work)
"hey share your idea!" (i told him that my idea clashed with another group mate's idea some dayS ago)
Really thank you so much for contacting me. seriously.  just for your own benefits. at least that's what i feel and that's the message i get. seriously, i don't need superficial friends like you that forge friendships for your own benefits. i'll still reply you because it's a form of respect. but please, get lost (ok actually i think you'll leave on your own when you no longer need me, and come back again when you realised you need my help again. tsk)

you'll never make true friends with that mindset of yours. at least that's what i have learnt.
