What's news about meeting and talking to an Afro-Carribean cyclist in deepest Somerset?

Today, during an hour's walk through the beautiful countryside near my home, I was surprised to meet an Afro-Carribean dressed in full kit for a long stint at cycling.

It was a very expensive bike with the latest in gear-changing equipment. 

1. Should I have been surprised?
2. Should I be ashamed? 
3. Should I have noticed?
4. Does the noticing mean I'm a prejudiced bastard because he spoke with an upper-class English accent.

1. But I do confess to being surprised.
2. I do feel ashamed by my reaction.
3. I should not have noticed.
4. I was wrong to be surprised by his upper-class English accent...

I hope that no one will notice and/or come up with better answers than mine in a generation's time (I am 70 years old) - especially when I'm related by marriage to someone as charming as Ade, who moved his family to Australia hoping to escape a life marred by color-prejudice in the UK.

Comments, as ever, welcome!
