I assigned a letter to my student that invites his friend to a dinner party at his home. He was expreceted to write the letter in informal style.
One of my students wrote, “Haven’t seen you for a long time, how are you?” Could I replace it with “Long time no see, how are you?” I think the sencond one is often used in spoken English, so maybe it is more informal than the first one. What is your opnion? Thank you.
