In relation to Halloween, let me say this, it's going to be different this year.
Mr Harris said that Halloween will be different this year and that trick-or-treating is "not a good idea".
"I've gotten lots of contact from lots of children asking about Halloween, and in the past when we've been blunt and honest with our kids they've responded with such resilience,” Harris said.
"It's been so tough for them, they've had communions cancelled, confirmations cancelled, schools closed, exams cancelled, graduations moving online and all sorts of different things."
He added: "In relation to Halloween, let me say this, it's going to be different this year. It's not a good idea to start trapesing around to everybody's house but that doesn't mean you can't have a good time.
"It doesn't mean you can't dress up in a scary costume, it doesn't mean your mum or dad can't get treats into the house or watch a spooky movie or play some games."
