I just need to figure this out and I appreciate all the advice
Yep...this doesn't sound like and emergency by any means but obviously something is going on that triggered you to make your original post asking for our help. It's good that you are paying attention to your inner voice because on some level you already knew what everyone has told you. Don't ignore your inner voice. Proceed with the friendship if you choose . To be forewarned is to be forearmed. From this point forward, you'll have a larger view of what may be going on and can then act accordingly, if need be.
The occasional gentle hint here and there may be all that's needed in this case.
You: (smiling) I couldn't believe it...the other day 5 year old Bobby asked me who made the world. I was surprised that he's thinking about things like that already and I'm glad he mentioned it to me.
JW: Why's that?
You: Children can sometimes get the wrong idea or be frightened when they're exposed to things they're not ready to understand yet. I think big picture topics like that should be addressed on a need to know basis and it's best coming from the Childs parent. I'm sure you probably felt the same way when you were raising your kids.
