We need each other.

Romeo and Juliet loved
each other.

We just bumped into
each other.

They can't talk to each
other any more.

You have to trust each
other.

Do you two know each
other?

We give each other
presents.

We smiled at each other.

We hardly speak to each
other.

They looked grimly at
each other.

We like each other's
company.

They looked deeply into
each other's eyes.
