Was explaining a technical concept at a "family" dinner. Suddenly stepmother wanted my help for something technical.

Stepmother: Say Awlex, could you help me install some software I recently bought?

Me: (Not this shit again) I even don't know what software you're talking about. How is the software called, what does it do?
Sm: it's calles digital... *long pause*
Me: (I don't like where this is going)
Sm: software... *another long pause*
Me: (fuck me harder than that lightly clothed woman outside)
Sm: something... *long pause*
Me: (alright brain, which way out of here doesn't involves me creating a bullet hole in either one of us?)
Sm: And you can use it to sell something...
Me: (tf do you event sell?!)
Sm: but not like ebay
Me: (what is it then? A platform for selling services? I don't even know what kind of software you'd have to install, given that most of these platforms are be web applications, whcih makes sense for selling stuff on the internet)
Sm: Anyway, could you help me install it? It would take me hours to get into it.
Me: (You think just installing would solve it? As soon as I install it, you probably expect me to be your walking manual as well, don't you?) Look, I'm gonna be honest with you, since I started working I don't have nearly as much free time as I used to have (Not everybody works when they feel like it, you know that?) I get home at around almost 7pm (most of the time) and don't really wanna work afterwards. Most of the time there's a support service from the people who made this software and they would be glad to help you. (Sorry support team, for pushing this bundle of incompetence onto you, but I guess she didn't even listen to my advice).

After that she didn't back down and still wanted my help. Then my grandmother derailed the conversation and got me out of this. When I thanked her later she yold me that she saw I saw uncomfortable and wanted to help. I love my grandmother.

So I am not going to be your "family" tech support. You b(r)ought this onto yourself. Are more than twice my age and still can't use your brain to solve problems like these on your own and you can even less reason abiut your motives and desires when asking for help. I am sick of you and shutty opinions about people, just because I work as a software engineer doesn't mean I'm exist solely for satisfying your unreasonable desires.

Stop offending me and my profession and get yourself some common sense.
Protip #0: Give me one fucking reason to help you, because you're not family enough and your personality really doesn't bring forth any emotion but annoyance
