Input: It was last week and I was on my way home. 11.30 pm, sitting in the tram and listening to some music. A lady, around 40-50 yo with a big suitcase approaches me and asks me something. As I remove my earphones she repeats: "Hello, I want to call my aunt and tell her where I'm going. Can I make a call with your mobile phone?". I was a bit surprised as 1) Everyone has a mobile phone where I live, 2) Wherever one is going, there probably is a phone and you can call from there, 3) Just generally had a bit of a weird feeling with the person. My conclusion was that the woman was either confused/crazy or tried to pull off some kind of scam. So I told her that I prefered not to (give her my phone). She then walks on mumbling "greedy asshole" or something.

AITA?
