My husband is a total morning person. Regardless of how much sleep he got the night before, how late we sleep in, how little we did in a day, he's falling asleep on the couch at 9pm. I can usually harass him into staying up until 10:30 or 11-- maybe-- but that's it and he's snoring in less than 2 minutes if I stop poking him or talking to him. In the morning he hops out of bed and is immediately in a good mood though.

I'm a total night owl. Regardless of how exhausted I am all day (first trimester excepted), I catch a second wind about 8pm and I am WIDE AWAKE from like 8-12pm. Really my normal clock would keep me up until 1 or 2am every night because that is when it feels like bed time to me, but I sort of hated my life when I let myself do that so now I try to make myself go to bed by 12 or so. But in the morning I hate everyone and everything until about 9am. Even if I somehow went to bed early at like 10pm, if I try to wake up at say 6am? I hate my life.

It's a little annoying to both of us because I want more/better company at night and feel like I'm married to some old dude who is snoring on the couch next to me at 9pm. He on the other hand gets annoyed that I'm so cranky in the mornings and stare rays of death at him if he tries to wake me up 10 minutes before my alarm goes off. Mostly it's fine because we're used to it and we know how to handle each other, but it's unfortunate that our natural rhythms are so out of sync.

I also just think it is interesting how ingrained our preferences are. I really think it must be something biological because he used to work a night job and was still a morning person even after doing that for a year. I used to have 7am classes and still hated life every single morning. Also my mom and grandma are both total night owls (my grandma stays up reading until 2 or 3am every day, how cool is she hah). So it seems genetic

How about you/your SO?
