So I'm Worth Less Than My Brother?

In order to take care of my father, who got hurt from a fall, I gave up on my chance to get promoted and even took a week's leave. On the day he gets discharged from the hospital, my dad hands me a mysterious envelope with a wide smile on his face. "Thank you for your trouble over the past few days, Luther. This is a little token of appreciation from me. You can buy yourself a nice pack of smokes." I rub my hands together, feeling warmth surging into my heart. But when I open the envelope, all I see is seven dollars. Still, I comfort myself in thinking that the sum isn't important at all. It's the thought that counts, after all. But the next day, I come across a social media post of my younger brother, Felix Grayson, who never showed his face around the hospital during Dad's hospitalization. It features a photo collage of a luxurious villa, with a photo of the purchasing contract smack dab in the middle of collage. The caption writes, "I bought the top-tier riverside villa for seven million dollars! Thank you so much for your support, Dad!"
