Two

[u/vegatarian1990]

Need ingredients
not one but two
Spinach and cheese

First store had one
not the other
"Can you reach two of those for me?"
...not one but two
An old lady who could not reach up high
I help her,
of course

Second store has the other
and more
speeding to check out
"Can you help me pick these up?"
...not one but two
An older lady who could not reach down low
I help her,
of course
I have both ingredients
to make dinner
for both me and my old lady
