Dear Shalini, it touched my heart. things really happen the way you described. being understanding and good observer(as i guess on reading it), u could manage to keep you ideals and manners up. but all dont have the capacity and sensitivity. society was to console theirselves as well as to ur sis that they care for them (as kids without mother) thats why they took the way irrespctive of thinking about the probable impact of such inquiries on ur sisters. such things leave an odd impression on childrens mind that they are suffereing. so they try to offend the situation and environment although it is friendly. so i think nobody is at fault but mishaps are avoided by the presence of a person like u who can understand the situation.
