ave made a statement？Hold the glance for the second longer，and you have made a different statement.Hold it for three seconds，and the meaning has changed again．For every social situation，there is a Dennissible time that you can hold a person’s gaze without being intimate，rude or aggre- ssive．If you are on an elevator，what gaze．time are you permitted？To answer this question，consider what you typically d0．You are likely to give other passengers a quick glance to size them up and to assure them that you mean flo threat． Since being close to another person signals the possibility of interaction，you need to give a signal telling others you want to be left alone．So you cut off eye contact，what sociologist Erv-ing Goffrnan calls“a dimming of the lights”you look down at the floor，at the indicator lights，anywhere but into another passenger"s eyes．Should you break the rule against staring at a stran-ger on an elevator，you will make the other person exceedingly uncomfortable，and you are likely to feel a bit strange yourself． If you hold eye contact for more than three seconds，what are you telling another person？Much depends on the person and situation，For instance，a man and woman communicate interest in this matter．They typieally gaze at each other for about three seconds at a time，then drop their eyes down for three seconds，before letting their eyes meet again．But-if one man gives another man a 3-second—plus stare，he signals“I know you，I am interested in you，”or“you look peculiar and I am CUriOUS about you．”This type of state ohen produces hostile feel—ings．

History also records that only in England about ten thousand people were put into prison during that century for stealing salt! About 450 years ago, in the year 1553, if a man took more than his share of salt, he would be thought to have broken the law and would be seriously punished. The offender's ear was cut off.
