hi folks,i have a potential problem thet you may be able to help me with.
yday a member of my family came to visit me at the lottie,only to announce he had already been there that morning and inexplicably had watered our greenhouse for us...nice you may think,whats the problem? the problem is that he watered in hot hot sun (((gRRRR))))  without being asked to...despite the fact that we DID ask him to do it when we were away,and he didnt bother once,despite living 2 secs away.now,cynical me thinks that this sudden interest is because we now have crops he may want to help himself too,he was certainly giving our turnips the glad eye yday,and we only have 5!!! how do you tell loved ones to b****r off with causing offence?
thanks rach x
