Born at this point in Leo season
Someone born on August 4 arrives in the middle of Leo, when summer is well underway and the sign's warmth feels settled rather than showy. Their pride is in being reliable. They keep promises longer than most people expect and notice when a friend has gone quiet. The difficulty comes when generosity turns into being the one who holds everything together. Asking for help can feel like admitting the fire is running low, so they carry more than they say.
