His dad doesn't like me

Omg guys I can tell when my bf dad doesn't like me. His mom will talk to me and ask me how my family is and is just more social towards me. His dad never says one word to me. I'll be eating dinner over there and his mom as usual super nice,his dad will talk to everyone else(my bf three brothers) but not me I just feel really awkward. Should I start conversation? Is he just used to all men in the house?
