homesickness

In childhood

Homesickness is a small stamp.

I'm at this end

Mom is over there.

When I grow up

Homesickness is a narrow ticket.

I'm at this end

The bride is over there.

We'll talk about it later.

Homesickness is a low grave.

I am outside

Mom's inside.

But now

Homesickness is a shallow strait.

I'm at this end

The mainland is over there
