We like to go geocaching
We like to workout together, and take our son for walks.
Hiking, building Lego, watching movies, cooking, travelling, reading, gaming…
Painting Dnd minis, playing video games, drawing, camping, cooking, drawing, watching movies
Playing videogames together (sometimes build up LAN setup), playing and take care of with my pet rats, watching movies, going out for other activities like swimming and so on, trash talk.
And when we talk about childhood stuff (we were pretty similar) we buy some stuff we loved in our back then and play with it. For example dig boxes with dinosaur skeletons.
