Flooding pushed their first day back a bit, but Long Beach students and staff finally returned to class Friday.

Four-year-old Avery says she was waiting for Friday for a long time -- her first day at Lindell Elementary School. She says it was good.

But the milestone had to wait after flash flooding forced the district to delay the first day. Roads across the city were flooded and hard to navigate on Thursday.

With weather out of the way, one of the biggest questions going into the year was whether or not kids would adhere to social distancing guidelines. Lindell Principal Karen Sauter says her students earned straight A's.

Sauter gave props to parents doing a great job preparing their kids for the school year.

"I think the parents have done a great job of preparing the children to come to school, wearing the masks. We have videos we sent out showing how we would be doing social distancing, physical distancing, and I think everyone is going to adhere to the rules," says Sauter.

Parents agree -- and Avery's dad says he feels safe sending his daughter to school.

Avery says she doesn't mind wearing a mask as long as she gets to see her friends.
