One good friend that’s constant

I can hold within my hand

No decision does it make

It’s contents I do plan

I fill it in the morning

Sometimes again at night

And if by chance I drop it

It causes quite a sight

I can hang in on a hook

Set it in a cupboard bare

It doesn’t seem to matter

That its niche is not so fair

I’m quite fond of this average vessel

And quite frequently I say

It’s fluctuating temperature

Makes us alike in many ways
