<human>: Backstory - I lent a friend $400 when he couldn't afford his rent back in June. He told me he would pay me back the following week. He fell into some rough times still after and pushed it back to July which was fine by me. Slowly he kept pushing the days back and trying to come up with new ways to pay me back until eventually he stopped responding to me. I lost my job over a month ago and have been struggling with cash and to top it off my grandmother is stage 4 Parkinson's and I need to purchase a plane ticket out to see her ASAP... so obviously the $400 would cover that easily. I attempted to explain this all to him and he still refuses to answer messages. On top of it all he posts about his new (more expensive) apartment he just moved into on facebook, constantly, and shows off all the cool crap he's buying or doing. Wondering if anyone has been in a similar situation and if so what did they do or say to get the money they were owed.

Can you provide a brief overview of the text?
