It does make me a little uncomfortable to see intimate displays of affection in public. It doesn’t matter if it’s straight or gay or whatever.
That obviously should have no effect on them. I have gotten comfortable with the discomfort, which is what people should generally do. It’s not their problem to deal with, it’s mine.
I can’t find the scene, but Supernaturalhad a scene like that. Sam had recently gotten back from Hell, and he got hurt pretty bad (forgot how, but something like a broken rib or gunshot wound), and a doctor asked him what his pain level was, with 1 being barely noticeable to 10 being the worst pain he ever experienced. He stares off into the distance and says something like “3.”
