Excuse me while I vent

I was scheduled for a meeting at 7:30 this morning. Normally I work from 8:45am to 6pm, because that's when I can get good shuttle and train service to and from work. Today, I drove because of the meeting. Since I was driving, DH asked me to drop him off at the bus stop so he wouldn't have to walk in the cold (the *high* today is supposed to be like 15 degrees). We agreed to leave home at 6:50, he'd wait in the station for his 7am bus, and that should get me to work a couple minutes early for my meeting, since it takes about 25-30 minutes to drive to work when I'm not dropping him off. Well, he's "almost ready to go" at 6:40 and sits down to read his online comics (which frankly he would be free to read at school--no one else is in this early anyhow), and at 6:50, I tell him it is time to leave, and at about 6:59 we are out the door. I get him to the bus stop as his 7am bus (which is fortunately for him running late) is pulling away from the station, but he flags it down and gets on. I put the petal to the metal, but it doesn't really help since it just means I hit all the red lights (timed to be green for people driving the speed limit). I get to work at 7:29, and my meeting at 7:34 (it was at the other end of the complex--I ran) and get turned away at the door because it has already started.
I came back to my desk and emailed DH about it. I tried not to lay into him too much, but I think it is important for him to know when he makes me late... after all, if he doesn't know his behavior is causing a problem, he can't fix it. He responds with, I'm sorry, but we left at 6:50, and you said it only takes you 30 minutes to get to work, surely it doesn't take 10 extra minutes to drop me off at the bus stop. Did he not notice that he almost missed his bus? His 7am bus that he was supposed to be 10 minutes early for? He should have known that I was really down to the wire for me to get to my meeting on time... I really wish he would notice stuff like this on his own.
I'm also miffed at the people running the meeting. They make a big huge deal about coming to the "all hands" meeting during your designated time slot, but then I'm 4 minutes late, and they tell me to come back this afternoon... but show up 10 minutes early because the afternoon sessions keep filling up (no duh, 4 minutes late is not very late around here, I'm sure there are tons of people who tried to attend during their assigned times this morning and yesterday and got turned away at the door for being a few minutes late... no really, it's appauling how often people are late around here--often I'll be 2 or 3 minutes late to a meeting, but still the first one there).
Alright. It felt good to get that out of my system. Maybe I'll be able to concentrate on work now.
