Where all have you played your Nintendo 3DS? Do you take it to a lot of places to keep yourself entertained?
When I've sat at the hospital waiting for a friend or loved one to get out of surgery, I've often taken my 3DS (or whatever Nintendo handheld I owned at the time) with me and played it while I sat in the waiting room. I can turn down the sound so that I don't bother anyone else with any noises from my games.
I took mine with me to a convention back in 2015 and I remember playing a lot of Smash in my free time and getting a lot of Streetpasses. However, I don't really go anywhere else. I'm also too scared to take it too far because I don't trust people and I'm scared it'll get stolen or something.
I've taken mine with me to a few places, however, the places that I've gone with it have been places where I know the people and I don't feel like they would steal it from me. Most of the time, mine stays at home though.
