Mother Texts Son Without Realizing He's Sitting in Front of Her

This woman didn't realize her son was sitting across from her on the train on their way back from the airport. The two of them started messaging each other with the son even sending her a photo and video of herself sitting on the train. Despite that, the woman didn't bother to look up and brushed it off as advancements in technology. It was only much later when she had a moment to take a look around did she realize what had just happened.
