Gone Fishing
Going fishing is an excellent option for spending a pleasant and, above all, relaxing day at a lake, river, etc. If you and your partner enjoy it, here's a good opportunity to surprise them. How? We'll make them catch a gift.
The idea is to find a small detail (of appropriate size, of course) and hook it well onto the fishing rod of the person to be surprised without them noticing. For this, we'll need some skill and choose a good moment to make the switch, or have an accomplice help us. Logically, the gift must be well wrapped, secured, and waterproofed if we don't want the surprise to end up soaked or, worse, at the bottom of the lake where we went fishing.
If everything goes as planned, we'll put the cherry on top of a perfect day of fishing in the countryside or at the beach.
