Classmate

On leaving school, she got married to her classmate.

I ran into an old classmate of mine on my way to the station.

Some of my classmate always make a fool of me.

Not all my classmate like the food in the cafeteria.

I ran across an old classmate on my way here.

I met my classmate.

I saw my old classmate last week. She's as boring as ever.

He runs as fast as any other classmate.

He is my classmate.

She married her classmate.
