I am confused about the usage of "Pass through" vs "come through" vs "go through". In the following sentences, which word is ok to use.
1) I (Abc) am standing outside my friend's (xyz) house ringing the door bell and he opens the door.
"Come in/pass through"Abc.I replied, can I "pass through the door/come through the door/come in" with the shoes on.
2) I am outside my professor's room.
Sir may I "come in/pass through".And I use "pass through", will i have to add the door as well or it's redundant
3) I am giving direction to some one.
"Pass through the door/cross the door" and take a left.
So when do we use "Pass through".
