In the line at the supermarket, the operator told the older woman that she should bring her own grocery bag because plastic bags weren't good for the environment. The woman apologized to her and explained, "We didn't have the green thing back in my day.â€ The operator responded, "That's our problem today. The former generation did not care enough to save our environment." She was right, that generation didn't have the green thing in its day. Back then, they returned their milk bottles, pop bottles and beer bottles. They were sent back to the plant to be washed and sterilised and refilled, so the same bottles could be used over and over. So they really were recycled. But they didn't have the green thing back in that customer's day. In her day, they walked up stairs, because they didn't have an escalator in every store and office building. They walked to the shops and didn't climb into a 300-horsepower machine every time they had to go two streets. But she was right. They didn't have the green thing in her day. Back then, they washed the baby's nappis because they didn't have the throw-away kind. They dried clothes on a line, not in an energy gobbling machine burning up 240 volts â€“ wind and solar power really did dry the clothes. Kids got hand-me-down clothes from their brothers or sisters, not always brand-new clothing. But that old lady is right, they didn't have the green thing back in her day. Back then, they had one TV, or radio, in the house â€“ not a TV in every room. And the TV had a small screen the size of a hankerchief, not a screen the size of Wembly Stadium. In the kitchen, they blended and stirred by hand because they didn't have electric machines to do everything for you. When they packaged a fragile item to send in the mail, they used a wadded up old newspaper to cushion it, not styrofoam or plastic bubble wrap. Back then, they didn't fire up an engine and burn petrol just to cut the lawn. They used a push mower that ran on human power. They exercised by working so they didn't need to go to a health club to run on treadmills that operate on electricity. But she's right, they didn't have the green thing back then. They refilled their writing pens with ink instead of buying a new pen, and they replaced the razor blades in a razor instead of throwing away the whole razor just because the blade got dull. But they didn't have the green thing back then. Back then, people took walked or took a bus and kids rode their bikes to school or took the school bus instead of turning their moms into a 24-hour taxi service. They had one electrical outlet in a room, not an entire bank of sockets to power a dozen appliances. And they didn't need a computerised gadget to receive a signal beamed from satellites 2,000 miles out in space in order to find the nearest pizza place. But isn't it sad, the current generation laments how wasteful the old folks were just because they didn't have the green thing back then?
