Think about it this way sir.
approx 3 hundred years ago...a young couple got married, had sex and had a baby.. their baby had a baby... on and on down the line...you were born.
Wouldnt you feel a bit guilty to just clog up your family tree ? honestly ?
Did it ever occur to you that some family trees ought to be clogged up?
No guilt here, my man. I did what I did because it was the right decision for me, and if faced with the situation and with the hindsight that I have since acquired, I would make the exact same decision again.
I sense that with you, it's one size fits all. Maybe when you acquire a little experience you will understand that's not the way people behave, or should behave.
