I gave the office cleaning auntie a heart attack this morning... in fact, everytime I switch the mineral water tanks on the water cooler after the current water tank has emptied. A filled tank weighs 5 gallons (how much is that in metric?) and I look too small, even (or especially) if I'm tottering round in my heels, to lift it. Well, it's not easy but I do. I used to wait for a male colleague to show up in the office to switch the water tanks, but one time I thought heck it, I'm not waiting for some guy so I can have a drink. So I tried it once and it gets easier after a while. I guess this applies to all things in life.
