It’s your friend’s birthday! But no matter how often you call, somehow you can’t get through. No answer at their door, either. Still, there’s no reason why their absence should put you off showing you care. Try any or all of the below…

1. Simply blow up dozens of balloons through their letterbox, tie and release into the hallway or front room.
2. Buy a beautiful big bunch of flowers or pile of thickly-iced cakes, and push them through the letterbox, one at a time.
3. Finish everything off with a full can of silly string.
