Not my mom, but my wife's whole family. I'm a software developer.

So we're invited to her grandmother's 85th birthday celebration with pretty much every family member they could think to invite. 100+ people, and we all sit down in a circle in a huge room to watch a video that my wife's father and aunts/uncles put together.

They start the video and there's no sound. I'm a software developer, so I'm not an expert in hardware issues. I try to turn invisible, because every tech person knows what comes next, and this is in the center of a room of people I don't know.

After about 15 minutes of people struggling to get the audio working, one of the people remembers I "work with computer". Soon I have a dozen people calling me to the center of the room.

I begrudgingly make my way to the computer and projector. Upon inspection, I find that the computer is connected via VGA to the projector.

Me: "This cable only carries video. You need a different kind of cable, or you can hook up an AUX cable--the kind you use for headphones."
Other Guy: "I used this cable earlier and the audio was working."
Me: "...that's weird. Well, can we try plugging in an AUX cable?"
Yet Another Guy: "Will this help?" Holds up an HDMI cable
Me: "Oh, yeah! That should do it."
Other Guy: "I tried plugging that in, but it didn't change anything."
Me: "Hmmm..." Quickly unplug VGA and plug in HDMI, then click play.

The sound comes out in its full cheesy music glory. Everybody cheers, and I walk back to my seat. Throughout the rest of party, I'm approached by various other family members who ask me if I can fix X since I'm a "computer guy". Isn't it great to work in tech?
