I have a family coming this evening that is interested in starting in September. I interviewed them a little while ago, and they have decided now they want to meet again. I agreed to see them at 5, when I close. I have very, very busy evenings, and I'm really running on a tight schedule by doing this. Anyway, they just emailed me and asked if they could push our meeting back to 5:30. I told them that I would like to keep to our original meeting time. My family typically eats at 5:30, and I need to be out of the house by 6:00 myself tonight. I'm also afraid that if I allow the meeting to be pushed back, they might think that my closing time will be negotiable in the future. So... am I being too picky?
