I confess that my reaction to this is colored by prior threads on CC in which a student didn’t want to attend college graduation or similar events because they “didn’t like ceremonies” or thought it would be “boring,” even though their parents wanted them to attend. If my kid did this–and it was just because she “didn’t like parties”–the consequences would be much more than just returning the gifts. On the other hand, if it’s because of social anxiety or some other health problem, the parents created the situation.
