Some chaps/chapesses are colleagues. But some become friends. Ive already paired up on a few extra trips with guys/girls ive had a cracking time operating/socializing with. Its each to your own I suppose, but if 60% of your time is away with colleagues, I want to make that experience for others and myself as enjoyable and memorable as possible. I suppose I see that as part of my "job".
And I don't work for VS!
