My phone is no longer mine. Has this happened to anyone else? Perhaps this was how my own mother felt when she picked up the wall-mounted (固定在墙上的) phone that could reach any room in the house, only to hear my voice chatting with my friend. Remember those days when we all shared one home phone? As a child, I would frequently visit a friend whose mother lived on her phone. I would wait and wait to make a call to my parents to ask for a ride home. Sadly, even though I am now a woman who is far closer to 40 than to 30 , I am still waiting to use the phone.
My husband and I are Generation Xers, fighting our way through a world filled with TikTok, Snapchat, and Twitter. We've tried to search through the latest parenting advice from experts and medical research available on the use of screens by young children. Finally, we agreed that 13 was the best age for our children to gain access to these technological wonders.
However, the COVID-19 pandemic hit. The world changed, and so did my phone. While during the lockdown, my phone acquired Zoom, Marco Polo and countless other apps that allowed my children to connect with their friends. All of our family, my husband and I included, were longing for meaningful connections with friends. So I arranged Zoom meetings for my kids, and then my phone began to disappear for hours as they shared Marco Polo videos back and forth with their friends.
Even though I'm frequently annoyed because my phone has walked off again, my heart is ultimately full. My kids and I are sharing. We're learning to co-exist, to set boundaries, and to think of each other first. Because of my phone, I' 
involved in my kids "lives, I know their friends. their habits, their favorite apps and photos they-have taken. Sharing my phone may be difficult, but it's rewarding; it builds another layer of connection between us.
