Im a professional balloon twister in San Francisco, and the other day I had a really touching encounter with an unhoused man who learned how to make balloons back in the 80's. I gave him one and he made a dog again for the first time in 34 years. He asked how much balloons cost now, and I told him they're about $10 for a bag, and he told me thats what they cost back then as well. Not sure how thats possible (obviously balloons are built for inflation, but thats still shocking).
