Memories

Memories are collected by Sims in The Sims 2, and stored in a panel in the Sim's information box. Memories can be good (in which case they appear in a box with a green background) or bad (in which case the background is red). Bad memories can cause sims to grieve. All memories, good or bad, can become topics of conversation, and sims who hear about these memories also get an invisible "marker" of the memory, which means they can gossip to other sims.

Bon Voyage adds a sub-box to this called Vacation Mementos.
