Spirit World

I read something today that reminded me of this idea. I'm not sure I ever wrote it down. It came to mind awhile ago.
I have heard some people that have lost their spouses comment about how when they see their spouse again - they're going to give them a big hug and kiss in greeting. Sounds great. I'm looking forward to seeing Layne again too. Here's the thing. What about the fact that it's the spirit world? Won't we both be spirits at that point? If we don't have bodies - it's going to be difficult to have physical contact. I'm not sure how that's going to work. I just know that there needs to be something to be able to feel connected. Something that makes one feel close to someone they love.
That is all.
