I totally agree. I am not always in the mood to socialize at soccer with other parents. Have had some great discussion and some brutally awkward ones. Sometimes I just want to watch my kid and listen to a podcast. Sometimes I drop them and go do something else. Sometimes I am kicking a ball and warming up my other kid.
But sitting in your car on your phone is so bleak it makes me want to like completely re design my life to eliminate technology.
