Fuyumiko is my best friend.

Let's go skiing next winter.

I started skiing last winter.

Fuyoshi-kun, have you finished today's homework yet?

Let's go buy winter clothes.

Brrr! It's cold today, isn't it?

Fuyuki likes to read books in the library every day.

This winter scenery is really beautiful, isn't it?

He participates in rigorous winter training every year.

I think that bird flying is a good omen.
