phone: showing pictures, letting them read some text, an article, basically anything i would send if we were not sitting next to each other. also letting them navigate when we're outside with a map. and letting them call or text someone when they don't have battery or connection.

laptop: mostly playing movies or letting them play games.

it's usually my friends and they wouldn't do anything bad with my device, but there was once this one guy in a group who wasn't really a friend and he looked at my gallery. that taught me a lesson, although he didn't find anything interesting.

with games and movies on a laptop it's worse, because that's sometimes for some kids. luckily they can't really use my custom linux keybinds.
