trouble is with family,dont you notice it only works 1 way,ive been there and done it many times and when i need something in return they either are too busy(yeah right)or say it will cost this much for the job to be done,the only person who i never charged was a very good m8(rip)who in turn carried out all the jobs needed to keep my car/van on the road,the only thing we had to do was supply materials,i never charge my mum either but bless her she will always give me some sort of decent good will payment which always ends in an argument when i refuse it,im quite willing to help anyone out if there genuine but when they take the pi55 it stops after all im not a charity.
