That is a good outcome. An opportunity to catch up with friends while they help you stay safe. Brilliant news about the trade show. Perfect timing. Sadly there are some really unpleasant people around us. I hope you have advised your friend who referred him of the situation so s/he (I forget which) is aware of this 64 year old's behaviour with women.
Have an amazing time over there. Friends and new business opportunities. What a trip.
