In this scene Mom is speaking to Julie and Sami about how much cellphones are taking away their time from being a child.
Julie is five and Sami is six. Mom and Dad wanted to go out and ride bikes at the park this evening but they were so into their phones that they tuned out their parents.
Mom and Dad are reminiscing when Julie and Sami were younger... They somehow couldn't remember the last time they saw them play with cars that boys like and dolls that girls usually like.
"We are concerned for your safety and what is happening around you" said mom.
Being a kid in this generation is different than Mom and Dads generation. We no longer do things "kids" do. Sometimes it is hard growing up in a generation where everything has to be checked once in awhile because of the scary things that are happening in schools.
It's important to know that you guys are just starting to experience life as a child. And it's a great thing to do because as soon as you hit adulthood, everything starts turning into a responsibility. Enjoy being a kid. Spend time with your family and loved ones. There comes a point where you will want to do so but it will be too late. Remember life is full of risks, don't do something you would do in front of mom and dad!
