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.
The way my spouse and my children’s hair smells. It’s a clothes the eyes and hug them tight moment. Almost always help fight back the darkness.
