Is this what I've become?
When I was buying my ticket for Malmö a homeless man came up to to offering to sell me his ticket. He had picked it up from the machine where another man had forgotten it.
I didn't really trust this man, so I said I didn't know if it was real, so we went to a station worker who said it was ok. Then I had to go to the ATM to get cash, with a sinking feeling of being fooled. But I bought the ticked, he showed me to the train and we said goodbye.
Now the conductor checked my ticket, and it was legit. My prejudice made me so sure I was being fooled. Even though I still believe my fear was understandable.
