Everyone can't stop talking about Prince George's 'grumpy' photos

The royal family is on the fourth day of their five-day tour of Poland and Germany, and a big trip like this could exhaust the best of us -- especially a little soon-to-be 4-year-old.

From the minute Prince George hopped off the plane in Poland on Monday, everyone could tell he just was just not having it. He was hanging onto his father, Prince William, and wasn't nearly as sociable as Princess Charlotte was.

While we could've chalked that all up to a case of the Mondays, little George still looked straight-up sleepy when the foursome landed in Germany on Wednesday. He was rubbing his eyes, pouting and leaning on his father for support. Classic Hump Day vibes, anyone?

Take a look at the photos everyone's talking about:

Meanwhile, 2-year-old Charlotte spent the week waving, shaking hands, accepting a bouquet of flowers and, wait for it ... curtsying! Can you handle it?

So, it clearly just hasn't been George's week -- and that's okay. We've all been there. We just hope the little guy gets some rest before his birthday on Saturday!
