I work pretty closely with one project manager at my office because the project in question has dominated my job for the past 2 years. I refer to her as my "work mom"; she's actually my mom's age, very friendly in a parental sort of way, and makes the best freakin' chocolate chip cookies I've ever eaten. It's a good working relationship.
Beyond belief, my old HP laptop was replaced with a 15" Retina MacBook Pro at the end of summer. I've been a Mac user for a few years outside the office, so it was pretty great to use my preferred computing environment for my job. This past week, this same project manager replaced her old machine with the same setup that I have, but she's an old school IT worker that's never really used an Apple computer. She's really smart - she's worked her way around IT for a lot longer than I have - but now she finds herself in a situation where she doesn't quite know how to use her computer, the tool she depends on for nearly every task throughout the day.
Now, as so often happens with actual parents, I find myself providing tech support. I'm actually kind of enjoying it, though. As I've mentioned before, I like to help people where computers are involved, so it's been fun to share the keyboard shortcuts, tools, and processes that have helped me out. It's also been instructive to see what I take for granted about they ways I work and what I've already learned over the years.
