Maybe I am just a prude, but I have been very uncomfortable around my very close friend and her husband. Lately they have been talking "dirty" to one another in my presence and it was not in a joking manner. It was downright appalling. They also kept leaving the room when I was visiting today to do what I don't know, but I kept hearing giggling and slamming. I am not opposed to public displays of affection but this was ridiculous. How do I handle this? I am happy that they love each other, but I think it should be saved for times they are alone. Also, when they left the room today, I was left with their 2 month old and 4 year old to take care of. Am I being prudish or is there a tactful way for me to address this with them?
