If you look at the Baltimore Catechism, and the catechism of St Pius X, and the catechism of the Summa Theologica, they all say the same thing: "Christ is a divine Person having the nature of God and the nature of man" (Baltimore Catechism No 3, question 83). I repeat, Our Lord had the human nature and the divine nature and His Person was divine, the second person of the Blessed Trinity
Laughing can be argued. But it has been argued by many saints that laughing is somewhat of an imperfection, and that Our Lord didn't laugh. Furthermore, if it was important for us to know that Jesus laughed, it would have been in the Gospel.
You persist in an erroneous notion of "person" that, rooted in Decartes and Kant, equates personhood with subjective behaviour characteristics as the word is used colloquially in English.
In theology, "Person" means an
individual substance, separate and distinct from all other substances of the same kind, possessing itself and all the parts, attributes, and energies which are in it. The Personhood of Jesus Christ is the divine substance shared equally and undivided with the Father and the Holy Ghost. It is not Jesus' incarnated behaviour which is grounded in His unfallen human nature.
The divine and human natures are united without confusion or subordination of one to the other in the one Person of Jesus Christ. He is fully divine and fully human. As St. Paul teaches, our Lord is like us in all things except sin.
At times you slide variously into monophysitism, miaphysitism, and monothelitism. You have been corrected, Dominique. If you persist in your erroneous claim regarding Christology, you will have to be regarded as a formal heretic.
