I know it probably sounds sad to a lot of people, and many of my friends really don't understand it, but the only times I've ever been truly contented is when wandering the hills and glens, or paddling my kayak on lochs, rivers or coast alone!
It's not that I'd take the hump were some other to turn up uninvited, more of a kindred spirit who'd be welcome at my fire anytime... and here's a dram!
I believe that most people are folk of many parts, ("...that man is not truly one, but truly two. I say two, because the state of my own knowledge does not pass beyond that point."; R L Stevenson) I have friends I meet up with at camping places or bothies, and some ripping times we've had. But the great majority of my stravaiging is done alone.
It's no problem so long as you don't let the Bogles get to you!
