He changed a lot since the last time. ✬

It's been ten years since we last met. ✬

Since you have nothing to do with this matter, you don't have to worry. ✬

Since you have a cold, you must not go out. ✬

Since I got a raise, I can manage. ✬

It's been raining since last night. ✬

Since it was raining, I took a taxi. ✬

Since it was raining, we stayed at home. ✬

Since it rained, we did not go on a picnic. ✬

Since it stopped raining, he went out for a walk. ✬
