@Stormkeep very good to know. My Sims tend to take photos of or with other sims and I often have them buy incredibly friendly to help with the friendship decay. I'm on long rotations so clubs help with this as well. Some are beloved but not many. So I can build friendship bars kinda easily but my kid sims would struggle a little without some help.
Why isn't it just an option like we have in social media? For that matter why am I restricted to one best friend but can have 10+ boy/girlfriends. I always like my spouses to be best friends but not always at the cost of losing a sister as a best friend.
I would love a friendship overhaul at some point to have the easy option of just deleting sims from the friends list and allow at least 3 best friend options. Still, being rid of unwanted townies is a start.
