When it sums up how you feel about your OTP:
When it gives you the history lessons you actually wanted to learn:
And gave us insight to what the founding fathers were thinking:
And then makes you question if any historical facts are ever right on the site:
And when you realize it has a science side:
And when it gets too real:
When it gives you the best Ron Swanson gifs:
And supplies you with the all the reaction gifs you could ever need:
When it explains the weird things us Americans do:
When it understands your obsession with books:
When it proves to actually be useful:
When it gets too weird:
And when it makes no sense at all:
And when it just makes you laugh:
Do you love Tumblr? What are your favorite Tumblr posts?
