Just a few things I'd like to clear up about the mechanics of when you get the +20 friendship and what prevents you from losing friendship. 1. If a villager has a conversation that lasts multiple clicks, do you need to go through the whole thing, or just the first one? 2. Does talking to a villager at a seasonal event count? My guess initially was yes, since there frequently isn't any other way to reach them on the day of a festival due to the area being cut off; however, I know that it doesn't count for the introductions quest, so I'm not sure. 3. What about non-seasonal (eg heart) events? 4. Does interacting with a shopkeeper (Clint, Pierre, etc) to buy things count as talking to them?
