If you do have sisters, the fact that there have been many intra-family squabbles about who gets dibs on certain items of clothing may not come as a surprise. (You know: two of you buy the same dress/top/shoes - questions of who bought it first, who's allowed to wear it when are the subject of heated negotiations.)
Recently, there have been some discussions among HTLT's nearest and dearest about who has rights over which colour of a popular brand of runners. I was told, in no uncertain terms, that I couldn't buy a pair of grey Converse runners because my sister had got there first.
