Homesitting is the act of staying at home in
one's own four walls in order to avoid any social interaction.
Homesitting is often performed by
people with social
phobia who e.g. order food only at delivery services and everything else on the internet.
If they once do leave the so called 'homeseat' they tend to stay in a safe 3-mile radius so they can easily return in case social interaction gets too much.
A homesitter usually owns a huge flatscreen TV, a very comfy
couch and plenty of other electronics in order to make the homeseat as livable as possible.
