building a duck

I have no idea how many times I have gone shoe shopping in my life. It must be at least three times as I currently own approximately three pairs of shoes. Well, if I purchased all three (approximately) of these shoes in the same shopping experience than I really only went shoe shopping once. So this makes it even more challenging to say how many times I have gone shoe shopping since I would have to have a number of shoes per shopping experience value that I am completely unable to determine. If I were to take a guess I would have to say that most if not all of the time I only have purchased one pair of shoes per shopping experience for I can not recollect any occasion during which I purchased more than one pair of shoes during one shopping experience. This is not to say, however, that I have not had any shoe shopping experience where I purchased more than one pair of shoes, it is quite possible that in my lifetime there has been at least one experience where I was on a shoe shopping excursion and I purchased more than one pair. What I am suspecting is that during some of my formative years it would be early fall and I would have purchased for me by my parents a pair of running shoes for gym class and a pair of proper school shoes for during school time. That totals two pairs of shoes for that shoe shopping experience. What is crossing my mind presently, with respect to shoe shopping that is, is how many more sentences I can compose that are relevant to shoe shopping.
