Occasional Evening Sitter / Big-Kid Companion for Independent 11 y.o. Boy

We’re looking for a reliable, friendly sitter to become our go-to person for occasional evenings, typically a couple of times a month. My son is 11 and pretty independent, so this isn’t a high-maintenance babysitting job. We’re really looking for someone he enjoys spending time with who can hang out, help with dinner or snacks, and make sure the evening stays on track while Mom is out. He enjoys having some independence, but we’d love someone who is engaged and willing to play a game, watch a movie, or just hang out rather than simply supervise from the sidelines. Most evenings would involve being at our home, keeping him company, and making sure he gets settled for the night.
