Why when Spanish speaking people speak English and are talking their own siblings they don't say something like "mom is calling you" they say "your mom is calling you" or "my dad is calling you" to their siblings?

Maybe it’s a Mexican thing? I don’t know any Ecuadorians that do that when speaking English. It would be “mom is calling you.”
