Undertaker and Lesnar's personal issues?

I believe Taker just said it was personal issues so that he wouldn't give away that he wants to face Lesnar at Wrestlemania..i don't think they actually have personal issues, i just think Lesnar was just in a sh*tty mood having just lost the UFC Heavyweight title by being dominated by Caine and then being asked if he wants to face Taker at Mania..that's probably why he just walked away..i'd be pissed too..I have no idea why Taker did an interview, i saw that interview and staredown earlier..it kills his character and when JR did it, like you mentioned he got his voice removed in the intro video..maybe Taker will get away with it because, well, he's The Undertaker..i don't think Vince will punish him in any way..maybe talk to him about it but nothing more than that..i was pretty confused when Taker said that they had personal issues..but then i got to thinking and i had remembered reading that they were thinking of having Lesnar face Undertaker at Wrestlemania and i just thought that maybe Taker just said "Personal Issues" to cover up for the potential plan..who knows, they could have issues but i doubt it..i think Lesnar was rude and didn't respond to the Legendary Deadman because he had just got his a$$ handed to him by Cain Velasquez..we'll probably find out if there are really issues between the two soon..great question..
