A person never takes part in any social events, they avoid people where possible and tend to keep themselves to themselves and make excuses that seem plausible but aren't consistent when a social event is happening; they say they don't have a baby sitter but their parents look after their DCs when they have to work, they say they have no money but they own a horse.
They need to lose weight but don't make any effort to do so, they don't bother with nice clothes and often wear the same things every day (which they have obviously washed and ironed in between), they don't wear any make up and they don't get their hair cut, and they don't seem happy. They tend to walk round looking at the floor not looking up and are quick to apologise if they think they are in the way. If they are criticised in any way then they tend to cry, they don't seem able to cope with it.
