PPT-Moving through the Membrane

Ahhhh Youve been soaking in the tub to try and relax after a hard day of standardized testing at school Getting out of the tub you notice that your fingertips and toes are like little raisins Have you just aged 60 years No way thats just osmosis in action Your fingers have absorbed the bath water causing the tips to form wrinkly folds . This is the moving business. It’s not easy, but it’s real simple: We take your things and put them on a truck, bring them to your new place, and move them in. Like everyone else, we wrap, we hoist, we pack – it’s just part of the job. We only make two promises. First, that we don’t charge mystery fees. Second, that we’ll work hard, because that’s what we love to do. This is the moving business.
