There is a girl on my friend list that updates her FB status frequently and usually it is about her husband and how great he is. He will "like" her status and they will write back and forth throughout the day. I have her hidden from my wall but occasionally I will visit her page for kicks. "Can't wait to go to Barnes & Noble with my hunky husband" and "Having dinner with the love of my life" are recent examples.
Is your SO on Facebook? Do you use FB to correspond with each other?
