No need for a bag-I have these here arms

I do my best to remember to bring reusable canvas-type bags with me everywhere-I have about 5 in the back of my car-but without fail those bags some how stay in my car when I go into stores (I have poor short term memory apparently). You'd think I would learn or at least be less reluctant to trot back to my car and get a bag when I realize I need one-but no on both fronts. So, I find myself turning down bags left and right and using my arms as my "bag". In fact I do this so often I have developed a patent response to the looks of craziness and the common remark of "Want a bag?" that I get from store staff as I walk toward the exit with my arms loaded down. I smile and say "No thanx, I have these two good arms, I might as well use them" sometimes I go as far as "God gave me two good arms because s/he wants me to use them" (if I think the religious bent will be more convincing) and then I go along my merry way. I like to think I am inspiring others to go without a bag as well, but judging by the looks maybe not so much. Sure would be easier if I was more consistent on bring my own canvas bags into stores with me... Wouldn't it be great though if we all used our arms and hands for what I can only imagine is one of their most functional usages-carrying things ?
