I’m sorry i left without you last night, but i told you to meet me early because the presentation started at 8: 00. i had worked / had been working to get it right for years, and i didn’t want to miss the beginning. by the time i finally left the cafe where we were supposed to meet, i had had / had been having five cups of coffee and i had waited / had been waiting for over an hour. i had to leave because i had arranged / had been arranging to meet katherine stern in front of the gallery. when i arrived, katherine had already come/ had already been coming inside and she was talking to the first guests near the entrance. she was really angry because she had waited / had been waiting for more than half an hour. katherine told me you had been / had been being late several times in the past and that she would not make plans with you again in the future. and in the future, i suggest you be on time!
