history: One time I saw a 64gb flash drive plugged into a computer. I really needed one so I just took it since it didn't have any information on it, but I couldn't help but feel bad about it.
current: As bad as it is to say, one time I took a flash drive that I saw in a computer that I used at school because I needed one and it had nothing on it.
next: That's interesting. At least you got some new storage space!
