What is the difference between 'expect' and 'look forward to'
Does 'expect' have a same meaning of 'look forward to'?
For example, I have been looking forward to seeing someone today, but I knew that he was too busy to come. However, he actually came today and I say "I didn't expect he will come today but he came"
Then, does it imply that I have been looking forward to seeing him? or just mean that I did not think he would come?
OR can I say "I've expected to see him" same as "I've been looking foward to seeing him"
I mean, does 'expect' have a same meaning as 'look foward to' or just means that you have a thought of something will happen in the future?
