Phew, I'm back. I wasn't on the trip alone actually, but with a group of 50+ people who... well, despite being adults, most of them seemed to act like kids, complaining from time to time about silly things, getting lost and almost always being late. Don't ask.
On the first day, we went to Keukenhof. This was actually the place I was dreaming to visit

It was raining a little a few hours so it wasn't really the most pleasant welcome D: But later it was nice and warm. Even though not all the plants were in bloom, it was preeeettyyyyyy ;-; Especially the pavillons with tulips and orchids. I didn't know where to start taking photos and all that stuff, really, so many different colors and shapes. And the smells made me feel like high or something. There were also a few cages with small birds, near the orangery. So much chirping fluff<3 I saw some tulip fields and windmills too, obviously.
Then we spent the night in a hotel in Egmond and went to the beach in the middle of the night, just to see where it exactly is. Next morning, after breakfast, we went there again for a few minutes to enjoy the place and collect sea shells.

I even saw a crab. Poor little thing was dead. :c
Later we went to Amsterdam and checked out its central part. Now I know why there is "XXX" in their coat of arms, lol...

There I bought tulip bulbs for my grandma. I wanted to go to the zoo but it was too expensive for my group (if I were on the trip alone, I would go anyway and regret NOTHING! xD) Despite of that I could see a flock of flamingos behind the fence. You know what surprised me? Wild parrots in parks O_o They were Rose-ringed Parakeets, I think. Even more fluff to enjoy~ Only thing I hated in the city was a flood of people, almost everywhere. I generally dislike crowds, they're irritating! And the traffic, oh god, I had a feeling that every single car and bike wanted to kill me.
Next day we went to Berlin, it was actually my second visit there so not really much of a "wow yay" reaction (the first trip to Berlin was fantastic, comparing to this). Saw a few parks, the Brandenburg Gate, Alexanderplatz, Sony Center, Holocaust Memorial and... I think that's all. It's impossible to see all the awesome things in one day.
Then we went back to Poland, I was home at around 4:00 AM. With sore feet and around 540 photos. Weeeee.
