Mark's a chatty bloke whom I ended up sitting next to, during this evening's long bus ride from Chiang Mai down to Bangkok. Mark's an Englishman; and like myself, he's also a seasoned traveller of South America. So the two of us had a good ol' chinwag on the bus, sharing our (all-too-similar) stories and reminiscences of backpacking in the Latin World. Sadly, from Bangkok Mark's headed out of Thailand: his plan is to gradually make his way home over the next few months, by way of India and various other countries.
