Hi,
If I'm talking with my friend about droping by his/her house, should I say:
- If I come now, will you have some time?
- If I came now, would you have some time?
- Should I come now, would you have some time?
- Should I come now, will you have some time?
- If I were to come now, would you have some time?
I really don't know what the difference between them is...
Thanks
