My new roommate drove the 25 miles to his parents' house every weekend to pick up his mail. I asked him why he didn't just change his address so he wouldn't have to make the drive all the time. He said, "because then, my parents' mail will come here!" So, I never explained it to this guy (26 years old), I just let him make the drive for the next year. Porn catalogs, everything, went straight to his parents'.
I live with another woman who is about thirty years old. She is totally stupid. She has done a lot of stupid things and I am sure she will keep on like this until she dies. One day she was trying to fix the cable of a ceiling lamp because it was out of order. The first time she had an electric shock because she tried to fix it without switching off the main power. I thought that she would switch it off before she tries again but, for my surprise, she just wore a pair of gloves and tried again. I was amazed by her stupidness. I could not stand it anymore and asked her why she didn't switch off the power and she told me: "You are right. That's a good idea.."
