It's been my observation that people tend to express affection in a way that they most need it themselves.
Some people are very touch oriented, and express affection through touches and being close, others might give give praise and positive encouragement. There are, of course, a myriad of ways to express affection.
Observe how the people in your life express affection, if you can express it back in kind it might just make their day. 😄
@viciousviscosity This can get a bit muddled if someone follows this advice, trying to show affection in ways that suit the preferences of their friends/partners. Then, their displayed affection no longer represents their own desires, but that of others (arguably a good thing).
But I do agree in general! Almost the inverse of of the "Golden Rule" - "Do unto others as you'd like done to yourself."

Agreed, certainly not a "catch-all" bit of advice, those are far shorter and infinitely more global - but something I've found useful in my general day-to-day actions. 😃
