No, just pouring a cup of tea does not unrust your skills. Their skills are much more than something ANYONE can do. A retired marathon runner doesn't unrust his skills either by taking a walk with his dog. And you don't have to completely screw up for your skills to be rusted. But whatever Lumiere and Mrs. Potts did, certainly doesn't unrust the skills of all the other servants Lumiere was speaking for.
No, you haven't actually.
And no, I haven' t put anyone down just for having a different opinion. I've simply disagreed with them, explained why and asked them to explain themselves, like I did just now with louiseculmer. Ofcourse, YOU have to come in and jump on me again.
Now stop deflecting and actually discuss the issue at hand.
