A present-time verb tells about actions that are happening now. We add s or es to most present time verbs when the subject of the sentence is he, she, it, or a singular noun.
We add es when the noun ends with a s.
We do not add s or es to a present-time verb when the subject is I, you, we, they, or a plural noun.

The boys walk home after school.
Jinny reads stories with her brother.
They read stories together.
The elephant drinks water with its trunk.
I drink water with my trunk.
When some verbs end with a y, we can't just add s. We need to drop the y and then add ies.

Chloe cries when she is sad.
The fox spies on its prey.
