When I saw that black cat, I somehow felt it was a bad omen.

He told an ominous story, which made everyone anxious.

Let's go watch a movie together!

Let's all work hard together to make the project a success.

Let's go to the park with everyone.

He said that black cat is a bad omen.

When he saw that black cat, he thought it was unlucky.

He is very anxious about tomorrow's exam.

He was feeling anxiety before the exam.

He is my best friend.
