The Bike is Totalled!

Darn,my brother can be so impatient sometimes.Today,my bike chain got stuck and the wheel is loose after my brother rode it to pick up my sister from school.I don't know what he do to made it happen but the thing is that the bicycl is already in bad shape when my brother return home.My brother was too lazy to bring it to the bike shop for repairs so he decided to do some home DIY fixing which went horribly wrong.He tried to open up the wheels but he broke the back seat in doing so.When he manage to set the chains right,he fixed the back wheel wrongly and now the bicycle can't move backwards and it can't move properly.So he open it up again and made it worse.Now the thing is that my brother have a very short temper.He gets angry very easily.He was angry that the bicycle was not in proper shape.After several attempts to make the bicycle move rightly,he eventually gave up and left the bike in a terrible shape.The bike have lost it's back wheel and the chain is broken.Now the bicycle is totally useless.

I sort of of upset over this.That bike has been my favourite if not the only bike even though it was not really mine since my brother bought it with his money but we do share it so it was kinda my bike as well.I once tried to fixed the bike when it had similar problem with the wheels but I know that a IF you can't fix a problem which you don't know,don't try to fix it yourself.This applies to those who hire people who have no knowledge of the problem.Something like this is best left to those who understands and have experience in solving the problem itself.
If there was a proverb about this,I would say: You can't hire a plumber to fix your computer.
