Below is a list of things you may have experienced.
As you read the list, when a word causes a reaction . . . when you notice a feeling in your body . . . use that word or phrase as a writing prompt and start writing.
Write about where you were and who was with you.
If you ate it, played with it, read it, or wore it, write about it.
Add sensory detail of texture . . . what did these things feel like?
Add your memory of taste, smell, sound, and what the item looked like.
And, of course, you may have also experienced these things as a teen-ager and as an adult.
