@KittyFinlay I feel like we are basically the same person, with the same husband! Imagine if we had a Whatsapp Chat!? 
My dad also told me once that perhaps I could be a bit less irritable with DH as we were arriving at my sister's house for a meal. What he had missed is that I'd already done a lot, then, on my way out to walk the dog had told him we'd need to leave very soon after I got back - only to return to a DH who was just going upstairs to shower while both DC were still in PJs. In DH's defense, HE was ready on time. It just hadn't crossed his mind that he had to do anything except get showered and dressed.
He's a lot better now, but man, it can be annoying.
Today DD is home sick. DH was on an early shift today. He texted me 2 hours ago to ask if it was okay if he did this one thing BEFORE he comes home (knowing that when DD is at hoem she can be really irritating for me trying to work). I said sure. He is STILL not home and based on his last message, he won't be back for another 15 minutes. At best. To be fair, DD is NOT being high maintenance today. But if she was, I'd be so cross right now.
