Why is it, when dinner’s ready, he isn’t?

It makes me so crazy when I have dinner ready and my husband doesn’t get his dinner right away.  I even tell him it is ready 5-10 minutes ahead so he will be ready to eat when dinner is done.  However, that is not the case.  He usually shows up 10-20 minutes later when the food is cold.  Sometimes I just want to take all the food and toss it in the trash.  However, when he makes dinner and I don’t respond right away, he comes in and tells me over and over again.  Now if I do that to him, he gets angry.  Is it just my man or is it all men??
