I tried very hard not to laugh after he got out of the car
What happened to cause you to laugh so much?
It was one of the funniest things I've ever seen. He was driving like an absolute idiot and then he manages to get the car stuck by driving into a ditch. He got out of the car and then it started pouring with rain, that's when I started laughing and couldn't stop.
I can see how the situation might be funny. Laughing at others can make them feel bad so hopefully they weren't upset by it all. You should probably apologize as well just in case it did hurt him.
Well I'm in a different country now and I don't think I hurt his feelings. I might send an apology through an email.
Sometimes what we find funny other people do not. Laughing at others can make them feel bad. It would be best to give them a call and tell them anyway just so you don't have a guilty conscious.
