A memory can be as simple as a moment you shared with a person, or as momentous as a major life event, including an anniversary, birthday, life milestone, engagement, marriage, or the birth of a child.

You can add a photo or video, as a memory, along with a description of it.  You also have the option to add the date of the memory. Additionally, you can also add a text based memory as well if you still want to contribute but don't have a visual asset.
