DH likes to eat alone for meals, but otherwise, we like sitting with other people during trivia, events, excursions, etc. and the majority of time when we invite others, or are so bold as to ask to sit with others, we get these excuses. Its not worth getting upset over anymore, but I feel like people in general are only interested in socializing in their established bubbles. But I do think we need to continue to try to make connections with others, even if 80% of the time it doesn't pan out. The other 20% might make it highly worthwhile.
