Considering other's feeling is very important

Today i made a big mistake ,because i said something without considering my teacher's feeling and hurt her respect.Now i am very sorry to my teacher and want to share my embarrassment with you.What is the most important is i don't want you to make the same mistake.If you are interested what had happened to me ,you can continue to read my blog.But if you do not want to continue,please remember considering other's feeling is very impotant.This noon,after the listening class,i went out of the classroom,and i met an english teacher who ever taught me last term,so i said hello to her and asked whether taught the culture of anmerica and britain .To my surprise,she doesn't teach this elective.well,the most important part is coming.It's time for lunch,so she wants to ask me to have lunch with her so she has more time to know more about my teacher's teaching way.but we are not going to the same cafeteria.I plan to go to the new cafeteria but my teacher goes to No.2 cafeteria..but i donot want to disappoint her ,i said i didn't mind going to No.2 cafeteria .She smiled.so i told her many things about my present english teacher ,and she was listening carefully.soon,we got to the cafeteria and we had to say goodbye because she is a teacher and often has lunch on the third floor where we students seldom go.when i decided to say goodbye to her ,she suddently asked me to write down her phone number.You never guess what i have said,so let me tell you.My first reaction is confused because i have told her evreything and i probably have no questions to ask her ,so i ask 'what can i do with your number on earth '.what a big mistake,because of my first reaction ,i hurt my teacher's repect.now i know,we should consider other's feeling.I am not good at writing ,please give me some advice to improve my writing.thank you!
