How Much Crap

I cant believe that there is so much crap to get rid of when you sort your house out, i mean if you move within the UK or your own country ,you just take it with you !!!!! But if your moving overseas and not taking anything except personal stuff what the hell do you do with it as its not worth jack to anybody else, but you have spent years collecting things you need so its worth more to you and i hate just dumping stuff and when you do car boots you just want to smack them when they say i give you 50p for it its second hand
