I'm not a big souvenir collector. When I go to a place, I want experiences, not overpriced, poorly made tchotckes that you can get anywhere. Now, if I see something unique, special, yes, I'll gladly snap it up.
When I was in Paris last week, I passed a lot of souvenir stands. All stuff I've seen before. What did I bring back? Pictures. Coming around a corner and seeing the Eiffel Tower at night. Having a drink in a drugstore. Breathing in Paris.
And bringing back from Paris what I already have.
