Common Courtesy

I have always considered it a common courtesy if you are going to hold an "event" and you actually want people to show up, you need to extend an invitation a couple of weeks ahead of time, so people will know what is going on. I think it is rude behavior to send someone a text message a day before you are planning something and expect you to be there. I have prior commitments I have to honor because I made those commitments. That seemed like a simple choice to me. The other party asked first and I accepted. Those are my plans, love them or hate them, I made a commitment.
