Topic: Can a memoir be really really short?

Hello, I'm Elspeth, new to this group and the site.  I'm in need of motivation and writing friends, and I really enjoy reading and giving constructive feedback.
I just posted a teeny tiny essay, My Life on the Sofa, and I'd love to hear what you think.  At two pages, this may be too small to be a memoir...?  But since it's my own life, it seems like a memoir.
Thanks for your time.  Glad to be here!
