Dp dropped his mobile on way back from work earlier. Someone phoned up to say they had it and dp has collected it.
Dp wants to drop in a thank-you note for returning phone which I think is good cos its nice that the person was honest and phoned a number on it (dp's mum) to say he had found it.
Lodger says we should give them £10 to say thank you. I think that is quite a bit (when we are not brilliantly well off) and a thank you note should be fine.
Lodger thinks I am unreasonable. Am I?
