My boyfriend gave me a gift.

Everyone was surprised by the news.

He went to try out his new air gun.

This factory uses compressed air to operate the machines.

He is always good at reading the atmosphere.

He is an expert in aerodynamics.

By doing wall squats for 10 minutes every day, you can improve your leg strength.

He is a person who can't read the room, so he struggles to match the atmosphere of the place.

The emotional atmosphere of this room is very calming.

Let's all go to the sea.
