We watched the sun setting behind the mountains. ✬

Thank you for setting the record straight. ✬

The sun is just setting. ✬

The sun is setting below the horizon. ✬

The sun was setting. ✬

Look at the setting sun. ✬

The sun is setting. ✬

I'm setting Tom free. ✬

Tom is just finishing setting up. ✬

There's no danger of this lamp setting fire to the curtains. ✬
