1. This is what I remember from the story:
- It is about dean and sam exchanging gifts for each other as pranks throughout december, and each tried to outdo the silliness of the gift (i think they had a rule that the gift must be used/worn immediately after receiving)
- At one point Dean gave Sam a reindeer headband, and Sam gave Dean a sweater with a red plusg reindeer nose on it (which Dean gladly wore since it's really warm)
- Purely Gen, and I it was a humour fic

Maybe I'm imagining this fic (I sure hope not) but I'll be really grateful if anyone could find it for me :)

EDIT : FOUND IN COMMENT


2. This one is a general search
please rec me a fic from outsider pov which shows how much Sam regard Dean highly and/or choose Dean over anyone (could be from Jess or Amelia pov, I've read some really interesting pov of them) -- Gen only please (preslash or gencest are fine)
AU, crossover, self-rec are all ok
The longer the better :)
