Nostalgia reminded me of love, which in French could have a lot of words starting with a. They all end of r.
Adorer, Aimer, Amour. I like those words and I feel they have a lot to do with nostalgia, just saying.
(Erik, nostalgia is more hurting than loving, literally "home-ache," as in, you're a soldier marching through the snow tired and starving and you actually hurt thinking of home)
