...When what's written is one mere step above baby gibberish...
I don't know...Should I ignore it? Should I be helpful and comment? But then I know I wouldn't be able to keep the snark out of my feedback so I'd hesitate to say anything.
The best thing I know to do is to look the other way. Yet being in the same social sphere as the writer can be daunting. There will be times when simple communication becomes daunting because this message has been garbled and I don't know if I'm supposed to be insulted and angry or sympathetic and pitying.
I'm being random.
