Definition: Given a real-life anecdote of a complex ethical situation, generate a suitable title that describes the main event/root cause of the situation. Imagine that the given text is a social media post, and you have to write the title of the post, so the users can decide to read the main text or not.
Input: I genuinely feel like the asshole in this situation. To give some context I was selling a phone I had refinished on eBay, and said I would post it today, due to unexpected personal circumstances I was unable to post it.

I notified the seller but I got sent a response saying "You've failed to post it today as you have promised, use next day delivery". I could tell he was upset and so I apologize and ensure him that I am going to use first class (as close to next day delivery as you get here) postage for the package.

He gets back to me a few minutes later and said "You have 0 stars, I have very little to believe you right now. You will use first class postage as I payed £4.99" At this point I was upset by his demands, I felt like he was shouting at me - which is something that makes me scared due to past experiences with shouting.

Freaked out I replied "I will send you a picture of the package, ready to send to you. You need to have some trust that I will send it, I am not out to scam anyone. Please confirm that the delivery information is correct" he then goes on to tell me that he was recently mugged and that I should have kept to me saying that I would aim to post it today if I was able to. 

Now I just feel like a dick for not posting it and for telling him to trust me

TL;DR I sold a guy a phone, was unable to post it, told him to trust me and then got told he was mugged.

telling someone who recently had something stolen from them to have some trust
