I agree with Shengoro, AXM, and RyoHazuki8, mostly because they have affirmed what I have said and it gives me incentive to include in a "Public Displays of Affection" section of my project tentatively called "For Your Convenience", formerly known as "Culture Shock"
There's room for both explanations. Never said that it was the reason exclusively. I don't think I'd be doing my best in a culture project without, you know, the culture.
