Link up with Me

Linking verbs do not express action
They’re made for our grammatical satisfaction
The point of attraction for the subject and verb,
Words made so our story can be heard
Max may run to the party
He might be late
He must be on time if
He wants that cake
We’ve been waiting for an hour
I was excited
Now I am frustrated
I have been acting kind of sour
I should or I would or I could get invited
We are all invited, everybody is excited
I can or I shall or I will bring a friend
So we have a good time, the end
