 In a new post on Reddit, the woman says her sister invited the woman and her family to stay with her for the weekend. It required a six-hour drive, but the woman was up for it. All weekend long, the sister, our host, was talking about inflation and how much it costs to feed her six kids. By all accounts, the sisters and the family spent a nice weekend together. But as the woman was saying her goodbyes, her sister asked if she would pitch in for the cost of the weekend. The woman asked how much.
