I was busy with my exams. Therefore/Hence/So I couldn't send you any words. From now on, you will start receiving once again. Is it correct and can I use any "therefore/hence/so"?
A Word A Day:
I was busy with my exams (do not split it into two sentences here) hence I couldn't send you any messages.
I have been very busy with my exams. Consequently I couldn't send you any messages.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
