Timing

So you know how when guys are tired they get kind of selfish? At least my guy does. If he's worked his 8 hours on less than 7 hours of sleep, he's kind of a selfish whiny bear. He just gets all silent, and 'moany' and 'sighy' and 'huffy' and just kind of lays around like a giant dead animal.
Last night was one of those nights. He worked 8 hours, on 6 3/4 hours of sleep and *gasp* I asked him to put the dinner - that was completely prepared- in the oven before I get home. Because of his above mentioned state of sloth, he forgot to turn the oven on, so, at 8:00pm, when I walked in the door for the first time since 10:00am, I found cold raw dinner in the oven and had to whip something up fast. Wasn't incredibly happy about that, but I shrugged it off and just went on with things.
So, we get through dinner and after working a 10 hour day, on the same amount of sleep as him, I still wanted to do something together. His idea of that was letting me sit and cuddle with him while he lounged in his sweats in bed reading football stats online. So I cuddled with him, he read the computer screen.
Does your husband ever do this? Let you cuddle all you want, while their attention is completely taken by something else? Kind of like, "I know you want attention, but I'm too tired to bother with you, but you feel good, so keep touching me while I ignore you" ? That's what my husband does, and it drives me insane!!! Especially since usually, when I'm ready to go to sleep and have just stopped caring if he's paying attention to me and have just given up any hope of getting any affection, he decides to wake up and cuddle back and wants even more attention!!!
Why do guys do this? Do they just not get it, not care, or do they just have a really pathetic sense of timing?
