My daughter has been suspended from school for three days for beating two boys who poured her lunch and I can't even argue with the school.

My neighbour at my previous residence was a land surveyor and I remember him explaining this to me one time. So, what causes this is that the 69 was measured using a theodolite and is the most recent reading while the 67, plainly shows that I have no idea what I am talking about.
