First day at work. The people are really nice, but my trainer wouldn't stop explaining the same thing over and over again and telling me things that I already understood. I think that my polite interest/how I respond to information that I already know MIGHT suggest to people that I don't understand what they're saying? I'm not sure though, as I've never been good at facial expressions/body language/etc, and I think that people would think that it was arrogant or rude to say 'I already got it, thank you.'
*Sigh*
