Hypothetical: My friends, family, and village are relatively poor. I own a large modern house on the water with new cars. I don't care about showing off and buy these things simply because they are functional or pleasing to me in some way.
When my friends or family visit they are impressed by my house and are in love with it. They are not overtly envious or angry with me or anything like that and simply are impressed by what I have because they have not seen these sorts of things before.
I feel negative emotions relating to the perspective of others and the social circumstances. I don't think "guilt" is the right word. The closest word I can think of is "embarrassment", but I'm not sure it fits. I don't mind being the center of attention, I don't feel violated, I don't think I've failed or am being criticized, I don't think this is especially awkward in any way, and I don't think I'm necessarily being perceived in a negative way.
What expression can be used to describe this "embarrassment" of having things that others do not?
EDIT: I suppose this feeling would describe any sort of embarrassment due to positive evaluation and not simply due to belongings.
