I have a question about Judaism.

Hi guys!!

I’m Catholic but my neighbors are Jewish and they’re very nice people. They helped me with so many things especially since we recently just had a storm in our state.

I have a few questions to ask about the religion but I am too afraid to ask them in person because I am afraid they will get offended.

1. In my neighborhood, there’s different (?) kinds of Jews. Some wear a long hat and don’t use smart phones, while some wear regular clothes and have an iPhone. My neighbor is the latter but I am wondering, is this two different kinds of Judaism? Or is it by personal choice not to use a smart phone? Some women in our neighborhood also cover their hair but the others don’t.

2. Are practicing Jews allowed to have non-jew friends?

Thank you so much!
