<human>: Can you provide a brief rundown of the text in within 3 sentences?

I only ask because I'm rather bothered by how my it is NOT a custom in my wife's family.  In fact, they rarely ever do.  Even when I make sure and say something to the effect of "goodnight" - most times they don't even respond. Other times, when they say "I'm going to bed", they don't follow that up with goodnight, or sleep well, etc.  They don't say good morning either.

No they don't think I'm evil or something.  It just really irks me because all my life it was a custom in my family, a reflex.  Also, if you didn't say goodnight before you retired to bed, it was an implication that you were upset about something (unless you just passed out of course).

Especially if you are together for the holidays or what have you.  This is what I'm referring to when it comes to my wifes side of the family.  I always went out of my way to say goodnight or good morning when I was given a room to stay or vice-versa.

I grew up in the mid-west U.S.A., they grew up further south in the U.S.A.
<bot>: Are "good morning/goodnight" greetings a universal thing?  Is there a geographical separation?  Is my wife's family full of Adolf Hitlers? Hell, I'm willing to bet that even Hitler said good morning.
