*coughes* Expert!? LOL Anyways thanX for the honour. xP
Hmmm...
What I know about this was, that Taiji and Yoshiki didn't have any contact to each other since Taiji left the band. So they first met again before hides funeral. As I know Taiji was in a really bad situation due this time, had not much money, so that he was asking Yoshiki even for a smoking to visit the funeral, besides I heared that his jaw was broken and that didn't heal the right way since he had no money for a medical treatment.
Finally Yoshiki helped him with the smoking as well as with some money for the medical treatment.
Hm... how far that story is really true, I even by myself can't guarantee, but that's what I heared about this.
Besides there are many people who think Yoshiki and Taiji were really pissed at each other so that Yoshiki kicked him out of the band... Finally I don't think so.
Taiji said in his book "X no Sei to Shi" that there were even problems with the staff who can't stand him... how far that is true, I don't know, but in my eyes there must have been something totally different as well between Yoshiki and Taiji, which both keep better in privacy.
But that the have hated each other... no... I really can't imagine....
