history: Recently had a to train a new customer on how to use our system. I was readu and had an answer for everything they threw at me. I love when I need to show someone how to do something and everything goes off without a hitch. Oh yeah_comma_ that's always nice. Sometimes they just don't get it_comma_ though.
current: Fortunately it's usually just not having the best answer for what they ask. I've learned and prepared a lot more this time.
next: Wow, you sound pretty confident! You must really know what you're talking about.
