I've always wondered this. During the introduction of the Hall of Fame Inductees, Finkel says that Hart "felt uncomfortable" being there at WrestleMania. Anyone know why?
That was when he hadn't buried the hatchet yet with Vince and Shawn because of the Montreal screwjob (and don't forget Owen's death). He wanted to be in the HoF, that was ok, but I think he didn't want to run into any persons at Wrestlemania.
He didn't feel that was right (yet)
Also maybe because of his brothers' death too (time heals I suppose and maybe Bret HAS forgiven Vince for any wrong doing in that incident, who really knows).
