We've been staying at a friend's house rent-free (while they are on holiday - lucky things!) for the last 2 weeks while building work is completed on our own house. I would really like to get them something special to say thanks but my brain is totally blank. DH suggested some flowers but I'd like to try and get something less "off the shelf" iykwim. I thought to maybe restock their fridge and freezer with M&S or Cook meals but is that a bit bland?
Extra context: we are 4 (DH, me and 2xDC); they are 3 (him, her and 1x DC). We've known them about 4 years. Eldest DC's are in same nursery room.
