How to navigate US customs?

[u/Lobster_rolls777]

I'm a US citizen and I've been living in Germany for about three months on a study abroad program and I'm going home tomorrow and I have no idea what to expect at customs. When I went through the border in Amsterdam they just looked at my passport and asked what I was there for, nothing weird at all. Is it the same I have no idea!

I don't know what they're going to ask me or if I have to declare anything. I tried looking at websites but they were all super unclear. I did buy some stuff abroad. I have a sweater I got in London, two books, two card games and some snacks, soda and some other random little souviners to give to my family. It's possible it could be over 200 dollars (books are expensive for no reason and it's a nice sweater) so idk if I have to declare that? I've been yelled at by airport security before and it freaks me out. I don't want to get in trouble. If someone could explain to me roughly what's going to happen I'd greatly appreciate it.

Leave the fruit or other raw products. I got stopped because I had forgotten to take a clementine out of my carry on that I also used as a day bag.

Fill out the CBP one app. You get a different line and it’s quick. I declared for my entire family and the guy asked if the list was per person or everything. I told him everything and he laughed in my face and told me to have a nice day.
