This happened to me too. Last Sunday, someone asked why my friend is so strict and how I stayed friends with him for so long. He's not really strict, he just hardly ever smiles. But when he does smile or laugh, it makes me smile too.
Why are some people like that? My friend is the breadwinner for his family, so he's gotten super serious over time. For him, life isn't a joke. People like him are living life on hard mode, and it changes how they act.
Yeah, some people are like that because of too much responsibilities which make them think all the time
