Last night when I had trouble with plugging the charger into my smartphone, suddenly I was curious about how can I grumble at it naturally in English. I could come up with these two ways.
A. Why can't I plug in it? B. Why isn't it plugged in?
B is far more natural in my mother tongue, but as far as I remember, I usually heard "Why can't I..." rather than "Why isn't it" in English. Could anyone suggest a more natural form and explain why it is, if possible?
