@PattyHanson that's not really the same thing. Checks have been getting rarer and rarer for decades. I haven't seen a check in almost 20 years. Something that was important for you to understand when you were younger just isn't true for your grandson. Your son probably hasn't needed to use a check for a long time either and therefore teaching his kids about them just never came up. He's not failing because he didn't deliberately sit them down and explain what a check is.
@aatch @PattyHanson i went my entire life without seeing a paper check until i moved to the US
i'm in my 40s
