Perception

It is amazing that we are influenced by the input we get from others.  For example the other day someone was telling me about the length of an item.  I thought he was talking about a different item.  When I went to measure the item I was thinking about I came up with length that I was told.  I went to measure the item again a few days later and it was two feet longer then my previous notes of how long it was.  The item did not grow in that time, I just perceived it was shorter based on previous data I have gotten.
