Two girls go figure

Question I am asking after you read the story is why would sandy (a chunky girl ) tell mary (a thin girl who is always told by strangers, relatives, friends she is thin/skinny, looks like a size 4) that sandy thinks mary is average and size 8, then pauses and adds in size 10.

Mary and sandy were in the hallway talking. Mary: “sandy I parked right across the street today” Sandy: don’t you think you should exercise instead of parking so close” Then they parted company, but mary was upset so she went to seek out sandy

Mary: “sandy why did you say I should exercise” Sandy: “because of the heart” Mary: “sandy do you think I am thin” Sandy: “you are average, size 8” paused and added “size 10“

Mary left and went back to her desk. Four co-workers saw mary and asked mary what was wrong mary told them what sandy said.

Her co-workers said to her: “mary you are thin/skinny and cannot be more than a size 4, and not more than 110 pounds” Mary: “so why did sandy say average and size 10 if everyone sees me as skinny/thin size 4” They replied: “have you ever heard of jealousy”

Keep in mind people out of the blue will tell mary she is so lucky she is skinny and cannot be more than a size 4.
