anyone else's have a guy so is so carefree

My bf keeps telling me how I don't trust society and am so cautious. I don't think this is bad I just don't want my car unlocked, don't want people finding out credit card info ect. I'm protective and very cautious. But wouldn't you be the same? It makes no sense to me on why he is so relaxed/trusts anyone. He watches the news he know how crazy the world we live in is. Can anyone relate or is it just my bf? We were raised in the same town, by the same type of parents, same income ect.
