Difficult negotiation

Though I said that I would never butt in the designing of new laboratory, he turns half deaf ear to me. The difficulties getting along with my son are observed here and there now. He often shows negative reactions unreasonably with repulsive remarks. Very difficult to negotiate with young guy avoiding his wrong feelings, sometimes being surprised by his wrong recognition in different way of thinking.
I have no intention to control him along with my own way, instead I hope he would go his own way in future. The gate of my mind is fully opened at any time for him, any questions and any proposal are acceptable.
Anyway I hope we go to good direction from now.
