Do you know by the way that we dutchies smoke less weed then most others, i studied in Enland for 1 year and i was really amazed by how much everyone smoked. I have never been in a coffie-shop. We only probably try it when we are younger, but it's not cool to smoke weed here, so not many continue.
Anyway, if you are planning to come to my beatiful country, Welcome and have fun.
It's true that we have a very free way of thinking, you can do and say a lot here. there was a naked skater with golden skates in Amsterdam some time ago, things like that are accepted here, if you feel like doing things like that, you can.
