What on Earth is "bei"??
"Er ist mit seinem Vater" is wrong. It has to be 'Er ist bei seinem Vater'.
Well now it's accepting "mit"...
please report it as an error. 'Mit' is definitely wrong.
Duolingo already told me this,I'm asking what "bei" is.
a preposition: http://is.gd/TlrMk4
Of course it's a preposition,but why "bei" and not "mit"?
That's just the way it is. Memorise it.
I suppose "with" indicates location here, that's why you use bei.
Mit sounds like doing something with your father, I don't think it can indicate location.
Can anyone smarter than me confirm the logic behind this?
I accidentally omitted the last word. Please prompt me to complete when that happens. I would hve easily fixed it
Why cannt we use seiner instead of seinem?
