Imagine this kind of introduction

Hello. My name is Marc. I live on an island. I write stories and anecdotes and take photographs. I read books, listen to music and I enjoy looking at internet sites about various things. I study Japanese mainly for fun. In my spare time I work as an English teacher.

Hello. My name is Marc. I have two parents and a sister. I have been alive since 1978.

Hello. My name is Marc. I keep my apartment just tidy enough to stop vermin infestation. My neighbour plays the saxophone and coughs really loudly.

Hello. My name is Marc. I like the colour green and have a slightly obsessive relationship with repeated symmetry. I sing songs in my head but sometimes I sing them aloud by mistake.

Hello. My name is Marc. I used to be clever in primary school so I only studied just enough to get by at secondary school, which wasn't a problem until I began tertiary college. I failed to keep up with a foolishly chosen course of study which led me into an interesting but vocationally useless degree course. Most of the things I have learned have been interesting but have thus far yielded no money beyond rent and a beer with friends every so often and I am OK with that.

Hello. My name is Marc. Who are you?
