Hi Jasmine, It means the same thing. The only difference is that the present form (with "do") implies that whoever is away, is still away, and the past form implies that whoever was away is back now. Here are a few examples: "I just came back from my vacation, did you miss me?" "It has been a week since I left and I won't be back until next week, do you miss me?" I hope that helps.

Did is for something in the past while do is for the present, right now. Hope this helps, Jasmine! :)

They only have difference in the tense. simple present tense (do) simple past tense (did)

Did past , do present ! Only

Yes, there is a change. Either he talks about the present, and did he talks about the past
