every day I get phone calls from some idiot to moan about something I fixed.

I had a job to copy a site and use it for another company, with everyone's consent. I do it and found the original was garbage. hard coded functionalities. limited control over which pages appear in the menu and so on.

problem is the site administrator doesn't understand the system and made pages visible on the menu that shouldn't be and so on. these never showed up before because it was broken.

now she phones every day because she setup her pages wrong originally and tells me stuff like, why did you change this, it worked before and crap.

I never expected she would have setup the pages incorrectly so I never thought this would happen.

lesson here is if it's broken and you're the only one that's noticed, just bloody leave it.
