I've recently graduated from university and am now working full time, while living at home until I finish paying off my student loans and can save up to move out.
While I'm still living at home, I want to spend as much time as I can with my parents, since I know after I move out, I won't see them very much. Even currently, I only see them for about 3 - 4 hours a day during the week, as I get home late from work often and they sleep fairly early.
The issue is, they spend so much time on their phones that I don't feel like I really get to interact with them much anymore. They're on social media during dinner, after dinner, while watching TV, and while in bed before going to sleep. When trying to talk with them, I get short or delayed responses, or asked to repeat myself because they aren't paying attention or aren't really listening.
When I try to talk to them about it, they get defensive and are in complete denial that they use social media as often and as long as they actually do. Short of gathering wifi traffic data to give them hard proof of the amount of time they are actually spending on social media, I've told them how much I've seen them on their phones when I am home and have asked them to try to spend less time on social media. I've emphasized that they might want to spend more time with me and my younger siblings while we're still living at home, because we will all be out on our own before they know it.
While they agree with me when I bring that up, they don't change their habits and lately it seems to be getting even worse. Even during "family activities" like going out to eat, going to the beach, watching movies/netflix together, or playing board games together, they're distracted by their phones for a majority of the time.
Is there a better way I can get my point across and convince them to spend more time with the family instead of their phones?
