Bringing Up Boys: When did you last see your father?

I don't think my husband quite gets it.
Our boys are growing up and they are growing up fast. In two weeks time Bog Boy will be starring for the second time in the school's Nativity play Whoops-a-daisy Angel. Bog Boy will be playing sole boy angel in the angel chorus made up of Year One's. He point blank refused to be a shepherd because last year he was an angel and he had AWESOME wings which he wore solidly for two weeks. At School. At Home. Everywhere. And only when he was in bed would he relinquish them. he wants to do it all again this year.
His teacher Mrs B is brilliant she just said yes the boys if they wanted could be angels and the girls could be shepherds as long as there were some of each. So my boy will be an angel at least to look at - I, of course, know otherwise.
I wish my husband could see it.
I know I told him when the Nativity play was being held but he forgot and now work  has got in the way. Unless Bog Boy is the Angel Gabriel next year my darling husband will never see his seriously manly little boy happily dress up as an angel. And I don't think he gets it.
ON Sunday, Dear Charlie had to go for a training ride on his bicycle for his big charity bike ride in June next year. he was away from 9 in the morning until 4  in the afternoon. The previous day he and Tatu ( he that helps int eh garden) had been moat clearing from 8 in the morning until 3 int eh afternoon and then we went out to a Ball at 6. The boys hardly got to see their Dad at all over he weekend. Now for most that's not so bad once in a while. The problem is Dear Cahrlie rarely gets to see them during the week because he works in London and gets back  after they have gone to bed and leaves before they wake up.
The Boy is beginning to take this hard for he turned to me after waving Dear Charlie off on his bike ride: "Will we not be seeing Daddy again until next weekend ,Mum?"
He has never once brought up the fact that he doesn't get to see his dad much so this statement knocked me sideways.
I tackled my husband on his return saying that he had to make room in his diary for his children. Work from home a couple of days a month so he could maybe catch a Hockey Match or see one of them in a play.
He did check his diary but said  between now and Christmas there wasn't a hope of him getting back at a reasonable hour nor of him being able to see the Nativity play or any matches.
They are growing up and he is missing out on things that once they are gone they are gone. perhaps he will get it before next year...
