All bout friendship

I like my friends very much... Although she didnt answer my questions, but i still will be patient to ask her the questions again ... I know that my attitude will change to very impatient sometimes but i also change it back very fast wat....I don't think it's just only me change the attitude, sometime they also change thier attitude wat.....Why am I feel so sad??I no need to worry they will angry anot, but I still very concerned bout their feelings...I really don't know why!!??Maybe I cant lost my friends again....I have lost my friend before in the primary school because of my attitude so I cant be like that anymore...I promise I will talk to my friends very friendly although I am in bad mood...I promise....
