Sims should autonomously do holiday traditions.
I do believe this should be added to the list of things they do autonomously. Especially the traditions of a holiday that the sim loves to do that have the heart around them.

I wouldn't really want my sims to do traditions autonomously - with Winterfest, I like to plan each interaction my sims do, and it would frustrate me so much if they started making the grand meal too early, or opened presents too early etc.
