In a situation, [for example] when the guy is continuously cheating and at the moment i say that sentence he is still cheating [/for example], should i say "he was cheating" or "he is cheating"?
There're 2 variants of that example sentence:
"i screamed at him because he was cheating" or "i screamed at him because he is cheating"
Let's say, for example, that i screamed at him 5 minutes ago. He began cheating 10 minutes ago and now he is still cheating. Which of these 2 variants should i use?
