Souvenirs are for people who:
- think they will never travel ever again (so everything has to be collected for the future).
I have souvenirs. I have a nightgown bought while at one of my German university still in use, a key chain found on the street outside my house in Shanghai and of course my lovely hand mirror from Hungary. Are they not souvenirs? I have a short memory, like telling people about my travels, usually work hard while travelling and never expect anything nice ever to happen again.
