Hi, could you please tell me whether the past progressive is necessary in the following sentences?<br/><br/>Bill was waiting here a minute ago.<br/><br/>I was not thinking of having a birthday party, but now I am glad I had one.<br/><br/>We were having a good time until my wife was stung by a bee.<br/><br/>Could we also use the past simple in these sentences?<br/><br/>Bill waited here a minute ago.<br/><br/>I did not think of having a birthday party, but now I am glad I had one.<br/><br/>We had a good time until my wife was stung by a bee.<br/><br/>Thank you very much
