Milestones and Other Packs - Concern I have

Well I thought a Milestone was similar to this:

An important event in the development or history of something or in someone's life - Per Merriam-Webster Dictionary

So a lot of what you listed sounds more like "memories" and not a "milestone". I personally would not want to be spammed with all of those things as notices, nor would I want them saved because the ones that actually meant something to my sim would get lost.
