I am writing a letter of thanks to my parents, and I'm looking for a word that describes "things I am thankful/grateful for". I was hoping "gratuities" might carry the right meaning, but everything I read suggests this most commonly refers to a tip left at a restaurant (not even a close second definition that points to the object that one is grateful for). Word enthusiasts, do you have any recommendations?
Because this is a letter, I would probably choose to say "things I am grateful for" before using an uncommon word, but I'm hoping there's a fairly standard word I'm just failing to remember.
Sample sentence: "I wrote you this letter to share some memories and overdue gratuities."
Thanks!
