Earliest memory meme

My Sabu memories in the previous entry lead, almost like The Chaser’s prize segue segments, to the meme Arthur has sent me.

I have to:

• Describe my earliest memory where the memory is clear, and where “clear” means I can depict at least three details.
• Give an estimate of my age at the time.
• Tag five other bloggers with this meme.

Easy, Arthur, as I have the relevant story on a page already, but here it is again.
