Recently, I've been feeling a severe sense of fatigue and I don't feel like doing anything.

I wake up at 6 o'clock every morning.

Don't you think his behavior has been strange lately?

Nowadays, he goes to the gym every day.

I can't read his feelings.

I have a feeling that he likes me.

I thought his behavior was really cruel.

Aldehyde is a very important compound in organic chemistry.

I think his behavior is unjust.

I think his actions are completely inhumane.
