Nothing. Absolutely nothing. Sometimes jealous, envy can have a play into this or they may think you’re a bit intimidating so they can’t really approach you. If you’re closed off and distant this may be a factor. But overall, you don’t need to seek the attention of others in order to be ‘good’ or ‘appealing’. Just do your own thing and don’t worry about others !!
