I speak in English to my nephew now and then. He take medicine regulary . and I ask him: have you taken your medicine?. Or, before he goes to bed ,I ask him: have you brushed your teeth*
Should I ask him by useing simple past tense?which one is correct? :
"Did you brush your teeth?"
Or he gets up before me. While ı was having breakfast I ask him "did you have a breakfast ?
According to me. the present perfect tense is correct. Because it is important for me that whether he does that action. or else it isint important when he does that action.
Which one should I use?Simple past tense or present perfect?
