Don't worry. The feeling will pass.

You might need to view this one in a larger format to read it.  It got a little wide.

C# isn't outdated!  VB isn't outdated!  Yes, yes.  Feel free to argue the language of your choice.  They all get outdated at some point, and if the language itself doesn't get outdated, there's the possibility that your skill set within the language gets outdated as it morphs into something you don't use on your projects.  After all, there's more than one version of C# and Java out there.  And even PL/1 isn't completely gone.  We still have the odd blue book floating around the office.  I've been turning some of them into hidden compartment books, but some people are very proud to have the original tome on their shelf.  It's not a condemnation, it's just proof that our job is sometimes less about the particular language, and more about the choice to be a lifelong learner who is willing to reinvent her/himself every so often.

Snarky: All this Javascript crap is starting to make me feel really outdated.

I quit listening at Excel...

This is one of those Snarkies were I considered many different punchlines.  Usually that happens because it's based on a real event, and I'm quietly telling myself at the time to shut up and not say all the things popping into my head.  No good can come from being snarky with a customer, unless the good is to lose the customer or your job.  Fortunately, I suspect only one of the customers I work with is capable of reading minds and she's an internal product owner, so I'll just get a squint, a shake of the head, and then a raised eyebrow or soft snort.

• I heard, "yada yada yada COM...yada yada I'm a GenX manager."
• Your macros should be put to REST.
• If it was an add-in, that means it can be a take-out.
• You lost me at Excel ("spreadsheet" for generic purposes?)
• I quit listening at Excel...
• WTF is COM?

Snarky: Tell them they can't change the REST interface. The COM add in we script against in Excel won't work. All those macros should be considered a dependency for any enterprise work.
