#this is also sort of related to my headcanon that Klingons headbutt each other to show affection

I think Vulcans should nuzzle their faces together when they like each other but it's like, not something you do in front of other people. That's something to do in private or if you're a little kid. Babies don't really know how to do this properly and are prone to just headbutting their parents/siblings instinctually. They want to 'get closer' to what they feel telepathically emanating from the people around them. This nuzzling is a form of telepathic communication but it's very unskilled (a baby can and will do it) and you only get broad feelings/thoughts from it. But that's alright bc typically the only feeling/thought you're hoping to get from or communicate with such an action is 'I like you'.
