haifagirl, so you concede that even when you had the financial resources you typically could not have guests. Now you don’t even have the room for it. And you state, like most people, you enjoy dining in the company of others. The combination of those two points should indicate you would be amenable to the idea of being invited out despite preferring eating at home – in the company of others.
The more fundamental point, though, is your objection to getting unsolicited invitations is unreasonable. How is the potential host to know in advance that you are from the minority that don’t even want an invitation?
