when helping just backfires

My brother told me something that pissed me off equally.
Okay he is in his final year of mechanical engineering, so everyone is busy with their final year project. His classmate was having problem connecting his gadget to his laptop via the LPT port, I think new laptops don't come with LPT port... do they? Coincidentally my brother's laptop has, so that guy borrowed the laptop from my brother and happy work on his final year project.

It has been quite a long time, so my brother went to ask that guy when will he finish using our laptop. He said haven't. After a while, my brother asked him again, and he told my brother that the prof said need to wait or stuffs like that, so couldn't return our laptop. Oh, he told my brother this: "cher, how much does your laptop cost!" And according to my brother, nowadays they bump into each other as if they don't know each other. The laptop is still not returned.

What the freak! Firstly, shouldn't he have the courtesy to inform/request the owner for extension? Secondly, the "how much" comment was really crap. Hello? Who is asking for help from who? If he really thinks the help is worthless, why didn't he go and buy a laptop with LPT port or whatever? It is like you feed a dog and the dog bites you...

That's why sometimes I am so reluctant to help people, knowing that most people don't appreciate it. On the other hand, my brother is quite willing to help "friends". There was once he lend a CD to his friend, who return it dunno how many months later. It was am empty case. Hello? He got hungry and ate the CD like a donut is it?

A friend in need is a friend indeed, but when he has finished needing you, you worth less than crap.
