I hate to be that guy, but I kept noticing grammar errors (such as 'starting a quote with an apostrophe instead of quotes", and once where a "were" should have been used instead of an "are" because the subject was plural). And I don't know the policy of tales, so I don't know if I am allowed to edit small errors like that. The thing with tales is that it's prose, so grammar isn't necessary to be as strict, so I don't know what to do here. Also, I am going to relay a pet peeve:
"When quotes have more "quotes" in them." You can write it in a less ugly way by "doing something like 'this'". Everyone seems to do this and I have no clue why. It made me confused as to when people were talking and when they weren't in some particularly crowded areas.
However, I started with negative because it's always better to end on positive notes, and the great thing about this tale is that everything except what I have mentioned is a positive note. SCP hijinx (don't know how to spell that) surrounding a Christmas tree that's trying to kill Krampus is pretty hilarious. It made me chuckle in quite a few places, and kept me smiling the rest of the time. Not even Christmas, but this has gotten me in the Christmas spirit. I hope Dr. Partridge keeps showing up, and continues to be a pear tree. Great work, Ihp!
