Similar situation happened to me my freshman year in college. I was on my way to class and saw my roommate/best friend (who sits next to me in said class) walking back to our room. She said there was a sign on the door saying class was cancelled. A week later I find out it wasn't. Come to find out, someone ELSE told her this, she assumed it was true, and therefore told me. I was pissed, as it was a class where you have to get notes missed from someone who was present, but couldn't put all the blame on her. Long story short, never take someone else's word without double checking for yourself.

I feel for you, as I have done similar things. But that is why I never take my friend's word for it. I always double check. That way, both the friend(s) and I can get our shit together.

At least you aren't the only one?

why is this labeled under intimacy?

What does this have to do with intimacy?

How come you're relying on other people to tell you when something is due. Don't you go to class? This is no one's fault but your own.
