I agree with Elena. I have two pairs of leather loafers and a pair of leather flip flops that I bought way before I even started thinking about my actions. Well, I thought about my buying actions, at least. (One pair of loafers were found at a consignment shop for only $4, they looked and felt new and they fit; The other pair I got for two or three dollars at a Spiegal Outlet store going out of business sale, since they were 11s,
which I rarely find, I snatched them up, and the flip flops, I found the day after my birthday last year on clearance at Wal-Mart they were only $2 and were my birthday present to me since I wanted a nice pair of sandals/flip flops.) Okay. I'm babbling.
I also have a wool sweater and a leather bomber jacket that I'm wearing. (Well, not in August in Ohio, but you get the idea.) The clothes are still in good shape. I have the philsophy of buying as cheap as possible and keeping them for as long as possible. A pair of loafers are scuffed and I want to take them to the shoe store (the real shoe store that does repairs, polishings, etc.) to get a good polish for them. Even if I wanted to toss the leather and wool and get new stuff, I couldn't afford it anyway.
I do have a gray area, as I said in the other post. If the wool or leather product comes from a thrift store, i.e., Goodwill, or Salvation Army, I'll buy it since the few bucks is going to the charity and not supporting the process of the manufacturing of the product.
Your mom sounds cool. I was raised with the philosophy to buy as cheap as possible and to wear the item until it wears out. Therefore, if I had wanted to toss the leather shoes because it was leather and wanted a new pair in replacement, nope, not unless the shoes were worn enough to justify a new pair. It's cool. It's been a good life lesson.
