My father is probably the most paranoid person I have come to know in this lifetime. His imagination is so wild that it becomes difficult to make sense of what he wants to convey. Most of the time, his paranoia is so compelling that we would just want to drop any activity we would like to engage in.
Our house feels like a garrison with too many padlocks here and there. Each of our bedrooms have peep holes installed, and part of opening a door would mean looking through the peep hole each and every time. There are also some doors with locks outside, particularly the bathroom, so in case a burglar comes in through the bathroom, he cannot advance further in house. These outside locks must be locked every night.
