As soon as Mike wakes up he immediately checks his phone. This is not positive behavior and should be done as soon as he is ready for school.
Even in his bus drive to the school Mike is stuck to his phone and is unable to converse with others or observe his surroundings.
However, Anna on the other hand is paying full attention in her class, and will wait for when she is given a chance to use her phone so she does not lose valuable information
Although Mike is in the classroom he is still unable to be fully present in his classwork and will in the end not be prepared for his class
A rather good example of not being fully focused on using technology is Mike and Anna both conversing in a conversation and working together to get their work done.
Since Anna and Mike are not actively using any source of technology they are both able to pay attention to their teacher who is helping them pass.
Getting a good's night sleep without distractions from your phone is essential, and although a little time on your electronic is okay, an obsessive amount time spent online is unhealthy and a good balance is needed.
