Well, the weekends are periods for relaxation. People like to take a break from work and everything they see a work, to be with family and have a good time.

During these weekends, parents may take their children out on picnics or to amusement centres and couples their spouses to catch some fun. During this period, it would be out of place to be interacting with those online. The right thing to do then is to turn off data and shut off any form of distraction. This is the most probable reason for people being absent during weekends.

Also, it's during the weekend that people like to travel. During working days, there may not be time for that due to the demands of jobs and what not. The weekend affords the time to be with distant friends and family.
