lol, to be honest i dont trust old people as far as i cud chuck them, they lie and they stink of stale p**s and cabbages. My parents bort a house from a coupe in there 70's they seemed honest and genuine. Oh was we wrong, turned out they was moving cos they had been broke in too 3 times in a year!!! When we asked them have they ever had any trouble, "oh no not here, its lovely"!!!! And if i had the chance ide rip an old person off, just cos there old dont make them thick.
i think she will be grateful enough if you keep it mint dont rag it about and just generally look after it, give it a nice home if your feeling really guilty then go back to hers and explain its worth more than you thought give her another fifty (or more depending how much you have and what mood your in) and she will think your the best person in the world lol
I have lost interest now. Wind up or not, I will be giving this particular episode a thoroghly good ignoring!
