Reconciliation....The First Step Is Often The Hardest

How does one go about reconciling with ones past? Or get back in touch with lost family or friends? Lately the latter has been a buzz in my mind, Family. As some know but many don't I have a sister whom I have not spoken with in it must be about seven years or more now. We live in different states now and with people asking about her has starting the cogs in my head. Should I try to get back in touch with her after so many years? What would I even say, there is no easy answer to that at least not an easy one I can find. The more I think about this the more it bugs me, Its gets to me more when I see sibling interact with one and other. Sure growing up we had our issues with each other who didn't when your growing up. Does time heal all wounds like some would have you believe? I know my Dad is not excited that I am thinking of writing her to reconnect and that's fine, they have their own stuff to work out. Its weird though I keep saying to myself "just write her and say hi and get the ball rolling" But it seems to be all talk at this point I have yet to take any actual action in this matter. Am I afraid she wont want to be brother and sister again I don't know, But it feels like something some force is holding me back from making that initial contact with her. Maybe my subconscious doesn't want me to its hard to say really cause I feel like it'd be nice to have that part of my life back while at the same time why change the way things are. I know this post has been more questions than answers try looking at it from my perspective I'm all confused as what to do about this whole situation reconcile or leave it be. Only I can make the final decision on what ill do obviously but here's hoping I make the smart choice that requires know which one is right the heart or the brain. oh well we shall see......
