I had to chuckle when I read this, my husband is the worst packer. He has the philosophy that you can buy whatever you forgot there. What? I hate that! You know darn well you will be in the hotel room without your favorite toothpaste and at 10 at night have to run out and get it! Argh.
Needless to say, I do not even entertain asking or discussing this with my husband as he would not EVER understand. I just quietly go about my business of packing for 6 people. I usually start a few days ahead so there are not freak outs.
As far as running late, my husband just does not do that, he is early if anything. If I am making him late, he will always call, he thinks it is insanely rude to blow that step off.
In short, he is the head of the household but I keep the peace. There is no need to discuss or even work through some things. I know he will not pack much, I just pack it and call it a day. I guess I do WIN. Ha ha!
