Things I have learned today:
When a water connection to your toilet is leaky, don't pull on it to check it. When you are in Orchard Supply describing the tubing to a salesperson there and they exclaim "wow, that's how they USED to do it!", that can be a bad thing. When you have moved on to Home Depot and the two sales guys helping you say that replacing the valve and new tubing (since the original replacement tubing from OSH was wrong) is a cinch, don't believe them. When the previously mentioned sales guys tell you "a little water could seep out when you disconnect the old tubing," proceed with caution. Maybe with a bucket instead of a Tupperware bowl. When you accidentally turn off your neighbor's water instead of your own, expect them to complain. When your other neighbor whom you consulted about the procedure comes back to your door to check on how things are going, it's a very good thing. I'm practically a plumber!! yay DIY Nation!
Non plumbing discovery: I really, really like the Mr. Greenjeans cardigan. Plus, the name makes me happy. Probably some 40 year old subconscious suggestion from Captain Kangaroo... If you have to ask, you're too young. [sigh]
