On a point of grammar
demonstrative pronouns and determiners
are singular this and that
and plural these and those.

You should know, however, 
that they love to show off
as in ‘this Alfa Romeo Spider Veloci
can really do a ton
on straight country roads’ or
‘those John Deere tractors
exceed expectation with their
high performance and reliability:
take it from me –
I’ve driven one’

That’s how we learnt our pronouns
the day Mr. Reid chalked up
our superlatives. He had a knack
for making us feel special,
fast-tracking us to look the future
full in the face
without flinching.
