There's an advertisement on TV lately, for a particular brand of men's deodorant - I think it's Old Spice/Red Zone - in which a girl was dragged to a camping trip with her boyfriend, and she was all weirded out by the bugs n noises, but her boyfriend was nonchalant and just chillin.
Well at one point she heard something growling and she freaked out and hugged her boyfriend, her eyes closed. Then memories began to flash inside her mind, one by one, each memories sweeter than the last, and she felt completely safe. She remembered why she stuck with this outdoors-loving caveman.
I miss a particular scent too... but unfortunately, it doesn't take the real smell to ignite my memory. Even a cheesy commercial can do the trick.
My brain's not too picky that way.
