My husband works remotely for a small company and the owners have kindly invited staff and their partners on a 2 day 'retreat' next week. I think there will be around 16-20 people going in total. I've just seen the VERY detailed itinerary which involves an entire 2 days (from breakfast at 8am until dinner ending at 10/11pm) as a group, doing activities. I'm very introverted, anxious about meeting new people, and honestly have no conversation whatsoever! I like socialising and listening to others, but in small bursts, over dinner etc. But this sounds intense.
I'm very grateful to have been invited, it's a lovely gesture. But help?
