What makes traveling in Amsterdam fun?

My friend just came from there but since he was on a company training trip, he had no exciting travel stories to tell. Kind of a lackluster trip to me.

I’ve never been to any part of Europe. I just have 2 or 3 friends who have traveled and lived there told me stories of how nice it was walking the streets in Paris, watching lovers duking it out in parks during the day, traveling by train from Italy to almost everywhere else, receiving free medical treatment in Switzerland, seeing huge buildings in Berlin ( what? )...

Which brings me to my main point of inquiry, if you’ve been to Amsterdam, have you enjoyed that visit and if you don’t mind sharing, what exactly did you do? I know marijuana use is legal over there and women companions could be seen behind glass windows.

My friend was there for three weeks and all he brought me was a lousy t-shirt, no fun travel tales nor any sort of sleazy anecdotes. Do you have any that might intrigue-? Thanks for sharing.
