'So had I' is like saying 'me too'. This means that a second person has started talking and they are in the same position as the first. The second person hasn't finished his report either, and has to give it in tomorrow morning. 'If only I had worked a bit harder on it yesterday' is like saying 'I wish I had put more effort in yesterday'.Excuse me it also contains one more line as follows
So had I, mine is supposed to be finished by tomorrow morning as well. If only I had worked a bit harder on it yesterday!
Could u explain this also. Importantly with 'So had I' i don't understand what it says.
I have done all my effort but i failed to understand it.
