For the 4th, I invited some friends of mine to go swimming and then go get dinner before go back to watch fireworks. Several times, one of my guests told his he was coming and had expressed that he would like like to meet up for dinner and fireworks. He even said, "Yes" on the invite.
When we walked over to the restaurant, he was nowhere to be found. When we texted him, he said he was working for another hour. When he finally got off, he said he was on his way and was taking an a rideshare but never showed up and never gave us any status. So after a half hour, we didn't feel like waiting and we were going to meet up with another friend who saved us a spot for the firework showing. So we texted him and he decided to forget it and go home.
