A Horse Named Lawrence

Not the best name for a horse, of course, perhaps it was Arabian so we'll say it again; they let me out, fifteen hands high, hoped it didn't buck, not a rider till you've fallen off, just my luck. Guys alongside were an entrepeneur and a branding man, I loved them both, never mind the bloody horse; someone took off down the track at great speed, it was an enigma really because there was no need. The horse was dappled white, room enough for two, those guys were more interesting than me and you; we need an elixir - the immortal reason for existence, how long does a horse live? Could you say it was good? Don't call me a lost soul - it's just irrelevance, because fortunately, I had a horse called Lawrence.
