<background>I'm an IT person. I have been doing technical support for years. For the most part, I don't mind when friends ask me to take a look at something. Often, it's a 5 minute max sort of fix and it would have cost them $100+ to take it into a local shop. To me, they are my friends and often my hosts and it's well within the boundaries of our friendship. If it's a serious thing that takes me more than ten minutes or so I usually get a bottle of wine or a nice lunch out of it. They are always gracious when it's something I can't fix or something I can't fix right away (it needs a part or something). Most follow my advice and take decent care of their machines so most fixes are one time only. This has been going on for years. </background>
My mother recently moved to the same state I am in and got together with a man with a large family, most of which is local to him. He makes her happy and is a nice man.
My husband and I went over for Christmas. It started with a quick 'would you look at my computer, I think Niece downloaded something again'. She did, I fixed it. Then 'would you take a look at Boyfriend's laptop, it's been slow'. Two hours and three computers later, I find his kids are now bringing over their computers for me to look at. They were nice about it, certainly, and apologetic when they realized they'd all had the same idea of 'oh, hey, GG is going to be there maybe I'll bring the laptop over and see if she can't take a quick look.'
But for the love of Pete, at one point, I had a stack of 8 laptops.
I ended up showing the tech savvy teen how to fix the most common issue and turned her loose, telling her it was absolutely okay to blackmail aunts and uncles with demands for jewelry before solving their 'way to many background programs running' issue, and watching her eyes light up with avarice. The aforementioned aunts and uncles were a bit annoyed at the teen until I pointed out they could pay her in $5 charms for her bracelet, or cough up my '50% discounted for friends and family' rate of $40 an hour.
I'm getting paid for the one that actually requires professional attention, and the other that required professional attention belonged to my niece and is mine until she's no longer grounded due to me uncovering the reasons it required professional attention. Once her grounding is done, it will be returned to her locked down with parental controls and a password that requires her to pay homage to her awesome aunt everytime she wants to log in.
