Imagine me, in a bus or a train, sitting somewhere in the corner (where else?), big headphones covering my ears. Reading. So caught up in what I read that I do not pay any attention to "outside" world. I bite my fingers or chuckle or even laugh. Not very loud, but still. And muchh too often, if I catch a glimpse of a look from other peaople - it is dissaproving look.
Why? What is wrong with having fun while, otherwise quite boring, trip? As if I was offending them with my behaviour. Or as if they were jelaous.
