In the first example, 'Since I have known Jane', we use the present perfect tense because I knew Jane in the past, and I still know her now when I am reporting. But in the second example, I 'came' once in the past - I am not still 'coming' - so the correct sentence is "Jack has been here since I came." |
Coffa, you're right... It was just a typo. Coming back to the main problem - I thought that if I'm saying "Jack has been here since I HAVE COME" then I imply that I'm still there! ... hmm... am I mistaken?
and tell me please - do we say
a) I thought that if I'm saying "bla bla bla..."
b) I thought that if I say "bla bla bla..."
and what's the difference and why?
