Why don't we have graduation parties in the game? I think we need those!

With Discover university and Highschool years we have a graduation day but there's no party to go with it! I'd want to celebrate at home (like we do in real life) after the official ceremonies. Throwing a basic house party as the graduation party doesn't really cut it as the goals include dancing and such and obviously there are no interactions that have anything to do with graduating.

What I'd like to see:

 A new graduation party type with interactions and goals that go with it. 

• Baking/buying a cake: we could have a special topping (maybe like the ones in My wedding stories) that stops other sims from autonomously eating the cake before the fresh graduate cuts the first piece. This should be one of the main party goals.
• If you have My wedding stories, the graduate's parents could give a toast speech.
• We could hang the graduation photo and the diploma on the wall and it would have special interactions like "Show off diploma" to other sims. If the sim graduated with honors or good grades, other sims could congratulate on their hard work. If the sim didn't get good grades, they could be embarrassed from showing off their diploma (especially ambitious and overachiever traits) but guests could say something encouraging whereas mean sims could mock them for their bad performance. Showing off the diploma should also be one of the main party goals.
• Parents/guardians would have special interactions about being proud to their child directly and also bragging to guests about their child graduating.
• Guests could ask about the graduating sim's future plans. (Handy opportunity to reuse Parenthood code here!)
• Guests could also ask about the final grades and this would either lead to happy and confident moodlets (with good grades) or sad and embarrassed moodlets (low grades) for the graduating sim.
• Guests could bring small gifts
• The graduate could also talk about their future plans or their degree to the guest sims. (So that future plans or degree could be discussed both autonomously as prompted by the guests or player-directed by the graduating sim)
• The graduate could tell a funny story from their freshman year or something along those lines.
• Upon ending the party the participants should have sentiments depending on the party's success and their role in the party. The graduate, their parents/guardians and the invited guests would each have their own sentiment type.
