Mothers, eh? They used to complain that we never phoned and now when we do they complain we’re not on WhatsApp. It’s a no-win situation. 
Maybe I do underestimate the level of annoyance, etc. Maybe I don’t care. Hypothetically, if people choose to exclude me by their deliberate, knowing (in)actions, and cannot see why this troubles me when I explain it, then they’re no better than those who serve me what everyone else is being served when they know I’m a vegetarian. If you can’t make allowances for your alleged friends, are you their friend? Apparently not, if you haven’t friended on FB.
