Okay so I want everyone to interpret their own way but just to say a bit about what I thought about before writing it... I wrote it with the idea in mind of a person leaving another person and wanting to leave them for so long and actually writing a goodbye note to them on a store receipt because they were desperate to say goodbye and a receipt is all they had for paper and they didn't care much about the person therefore just choosing to write a goodbye note on a reciept (Kind of like this person decided to leave and they were in the car when they came to this conclusion.. they had no paper but a receipt)  After a while this person puts aside the idea of leaving until one day they get frustrated and leave... leaving that note written on a receipt (the receipt stamps the date and time they visted the store therefore letting the person who was left know that they had thought about leaving for some time)
