Some students have a similar confusion with the words "bring" and "take". The problem exists because, with these verbs, the correct choice depends mainly on where the speaker is at the time.  For example, if, at the time of speaking, I was at the school, I would say "After the lesson tomorrow, I'll go back home", whereas if I were at home, I would say 'After the lesson tomorrow, I'll come back home".  If you really cannot decide which verb to use, one way to overcome the problem is to use the verb "return" instead of "go back" or 'come back", and the verb "enter" instead of "go in" or "come in". However, "return" and "enter" are quite formal words in English, so only do this if you feel you have to.  SENTENCE STRUCTURES:  •Yes, it's possible to kill a man with one's bare hands; that is,without using a weapon of kind.  •When I go on holiday I take clothes with just the bare minimum with me.
