The Hinter: This person will never tell you about their Christmas loot, but don't be fooled. They are consumed with publicly showing off their gift in the hopes that you will ask "Oh, did you get that for Christmas?" This is the cue they have been waiting for, as they will now take 35 minutes of your life describing to you in detail how their new cell phone is the best phone on the market.
The One-Upper: This person will ask you what you received for Christmas. Regardless of what you say, they will undoubtedly compare gifts, highlighting how your gifts are not quite as good as what they received. They will say things like, "Oh, you got that computer? Big mistake. I got an Intel I7 Quad Core desktop with the top of line Nvidia graphics card, 32 gigs of Ram, and 4TB of storage. It's way better than what you got!"
The Blessed: This person comes up to you, tapping into their capacity for false humility and says "Can you believe how blessed I am? Let me show you a picture of this new sports car my parents purchased for me. I am so blessed! I truly am the luckiest person in the world. So what did you get?" At which point, you find no joy in sharing about the 6 pairs of socks and the beanie you got.
The Flaunter: This is the person who receives clothing for Christmas, and lots of it. How do you know? Because he/she is wearing every single item simultaneously. And don't you dare ask if they got that new sweater for Christmas, because the Flaunter will now go through all the clothing he/she received, item by item. Everything from sweater, to socks, to underwear, the Flaunter will highlight how amazing this new wardrobe is.
Beware, for these people do exist. Come by tomorrow to find out how to defend yourself from such shameless propagators of Christmas goods.
