some thoughts about my interaction with opposite sex

I have over the last 4 years that is my college years become quite recicent as far talking to girls is concerned.I was quite a talkative person in my school days and had little hesitation in talking to girls but in colege slowly and slowly everything changed.While most of my freinds became quite open in the college life with me it was exact opposite.Very steadily and unknowingly i distanced myself from girls .
