Not sure whether this is strictly a gardening issue, but where else to post it?! Dh was busy this afternoon trying to uproot an enormous conifer tree stump from our front lawn when our 16-year-old neighbour who we've never spoken to before volunteered to help. He worked solidly for a couple of hours, fetching tools and chatting to our dc's as he worked. His Dad then joined in, and eventually the job was finished and they both helped carry the tree stump off the garden and tidy up. Dh obviously thanked them both at the time, but on reflection we feel we should show our appreciation more but how? If the lad was older perhaps we'd take round a bottle of wine or crate of lager, but as he's under age thats out. Was wondering about a gift voucher but what for? Or bake them a cake (or is that a bit twee?). We've only got very small children, so no idea what teenagers might appreciate, and would you get something for the Dad too? All ideas gratefull received!!
