Took DS to the park this morning. Quite a few other families there. One several benches and pieces of play equipment, there were toy trains (new) and small cardboard boxes which had a note attached saying 'open me'. Out of curiosity, I opened one. Full of sweets (individually wrapped, like lollies refresher bars etc...) Had to explain to DS (5) that while it was a lovely gesture, if we don't know who left them there, it's not safe to eat the sweets. No one else had touched them either for obvious reasons. I'm sure the resounding answer will be yes but, just to check - that's a weird thing to do, right??
