M:Mary,I feel worried about you.You haven't spent much time with Sophia lately.You two used to do everything together.
W:We did,but since she started her new job,all she has done is hang out with her new friends from work.
M:Maybe you should invite her over for dinner.Just the two of you.
W:I tried that a few weeks ago,but she brought a friend from work with her!She doesn't seem very interested in our friendship any more.
M:She's probably just excited about her new job.You should give her some time.It will be a pity to lose such a friend.
W:I've given her enough time.I think it's time for us to go on our separate ways.
M:Don't do that.I've heard that she is going to climb the mountain with her friends this weekend.You should ask if you can go with her.
W:OK,I'll go to ask about it and take the chance to make peace.
M:That's right.
