There are many people who are very shy and do not like to talk with other people. I know quite a few of those people because I work with them. Unfortunately for them, they still have to work and thus, they have to open themselves sometimes merely for their job. Yet, they are quite silent and they will not speak to you if there is no real need to. I would love to say that I adore this kind of lifestyle but I do not. For me, this is a bit too much. I understand that you can be a bit spaced-out and do not want to talk with people. There are people who simply do not like to talk with other people. They are antisocial. However, the people who I work with are simply shy. They are basically afraid to open their mouths. I imagine how these people do shopping. I imagine them sitting in front of their computers and ordering stuff online because they are afraid to say "hello" to the woman sitting behind the checkout. And those who drive cars? Oh my... they probably have to order everything over the Net. In fact, ordering tyres online is not such a bad way after all. I once lacked time to go to the tyres shop and buy tyres for winter and I have ordered those tyres online and I have not regretted it.
