Ha ha there is an element of that true. I chat fairly easily to people but as you say most have their own group of friends on these coaches. Transit and loon coaches, those were the days. Impromptu stop offs when you spotted some of the opposition for a little off here and there lol!
Was a day out back in the seventies going to Ipswich, West Ham and Newcastle and many others in a old transit van, but was as teenager then and for some reason doesn't seem as appealing now !!!
