Spanish spoken here

I heard two people at work talking this morning in a different language, one I assumed to be Spanish. It was great. The first person said, "hola". Then the other person said "hola, como esta?". It was like two high school students practicing spanish in class, except after that they held a conversation in that other language. I forgot to mention earlier that last week our building had it's windows cleaned. No big deal. But it was great to go into work in the morning and see these guides in all black on the roof. I immediately thought we had been taken over by ninjas. Unfortunately I was wrong, but we have really clean windows now.
