My brother's best friend had been coming to our house for years. I always saw him as an annoying older guy who ate our snacks and controlled the TV.
After I joined college, something changed. We started talking seriously about careers, relationships, and family pressure. I realised there was a completely different person behind the jokes.
When my brother found out we liked each other, he didn't speak to either of us for a week. He eventually accepted it, but family dinners are still awkward whenever someone mentions how long we have known each other.
