Turn everything off and then go look at your meter. It should have a dial like the small red one in the picture linked below that will spin with even the smallest flow. If it's moving, you have a leak. If not, call the water company and challenge the reading.
check out /r/dnd and /r/dndnext, maybe check out some podcasts. I can personally vouch for the adventure zone for a beginner friendly 5e podcast. I say 5e because 5th edition is a TON more streamlined than the previous editions like 3e and 4e, which are closer to the stat crunching nerdishness that is normally associated with d&d. Still alot of dice roles, but much less book keeping. alternatively, you may want to look at pathfinder, which is a happy inbetween of 5e and old d&d that some people who didn't like the new streamlined content created. you also may want to check out dawnforgedcast. he had some controversy a while back about him stealing views and stuff, but he's still one of the top guys when it comes to explaining d&d, especially to newcomers. He can help you learn the basics and create a character.
after that, you'll want to find a game. I personally recommend finding an in person game, but it looks like the katy area doesn't have too much of that going on, so I recommend roll20. applying for games can be kind of tedius and it does feel a bit like a job interview but in my experience, as long as you look for a group friendly to new players (its a tag you can sort by) and there is a reasonably experienced DM, it should go good.
as for if anyone will be rude or dislike you for being rude, I don't really think so. There will be dicks everywhere, but its hard to be a dick and also work with others to create a good story together, so the dicks get weeded out pretty quick. most people want to help as much and fast as possible so the group can follow the story.
I can answer any other questions you might have, and considering ive gotten a few comments with questions and a few pms, I might make a post here later about it. cheers!
