So, I go to hit against a tennis wall at my local courts and there is a guy on the one side with his 4 year old daughter on a toy scooter. So I go to the other side and start setting up (taking my racket, balls, etc out) and I get a call from my sister. And then I noticed the daughter scoot up to me so I tell my sister "give me a second" while the girl asks me for one of my tennis balls. For context, I have 6 balls and the dad is hitting away on the other side. I just straight up said "no, you should ask your dad" and she scooted away (not sad or despondent at all). My girlfriend, my sister, and some friends think that I'm an asshole for not giving her the ball. I would have definitely given her one if I was leaving but not right as I started setting up. So, Am I The Asshole?
