A childhood belief about hair

When I was 3 years old my family had just returned to live in the USA after being based overseas and so 'getting to know' my nearest relatives was the first thing we did. My Uncle then only in his early 30's who loved kids usually wore a hat or none at all revealing his baldness when he visited with us or when we visited him at the Grandparents. Well, one day we went to visit and he comes bouncing in and couldn't wait to pick me up but this time he looked different, he had a toupee on, something I hadn't seen before and based on what my mother says I gave him a very strange and curious look, reached out to touch his hair and then he, always a joker, pulled it off while playfully asking:"What's that?" and laughing at first my mother says I paused for a while and said "That's a Hair Hat!" So it was a 'Hair Hat' to me for many months only because it was a family 'joke.' My Uncle loved to tell that story whenever people with parents with toddlers were around and probably still does.
