I recently bought plane tickets to go home for spring break, but I forgot that the last weekend of my break conflicts with the first weekend some family are in the city of my university. They aren't coming specifically to see me, and there are more days where I will be present than absent while they are there, but my current plane tickets have me coming back 3 days after they arrive. My dad is ballistic about this. I can always cancel and buy another ticket, but that is an obscene amount of money. AITA for making these conflicting plans by accident?
