Moyes takes the Red Devils to Goodison Park on Sunday expecting a hostile reception from the home supporters after being booed for the return fixture at Old Trafford in December.
"I went to see Everton [play] last Saturday at Sunderland, but I've not been back to Goodison this season," he told reporters.
"It's nearly a year since I left. I've just felt that it wasn't the right time to go back at this moment in time. Time is a big healer.
"I think there was animosity at the way we would have liked to have bought a couple of the players. But some Manchester United players go to Everton, so there is reverse."
Kickoff tomorrow is scheduled for 4.10pm.
