Mine is lilacs, because there was a lilac bush at the bus stop that I used to wait at with my mom when I was a kid, it was my school bus stop and the public bus stop so we spent a lot of time on that corner and now when I smell lilacs I just immediately feel like a kid again.
My stuffed animals after I’ve been snuggling with them for a while. They smell like love to me. Probably smell like weird BO to others, but they don’t to me.
