Why couldn't they move close to you? You had a job and life settled. They are retired and therefore far more flexible in that aspect.
There might be some factors you didn't share of course. If I was asked the same I would help but it's my parents who would have to move. If they are not willing then clearly that help is not needed so badly to justify such a drastic change in my life.
You may want to research emotional intelligence. There's lots of methods you can try but they are not quick to explain. Some examples.
Above all stay calm. The more the other person gets angry and confrontational while you stay calm and professional the better you look in eyes of everyone else. It makes it obvious to others who is the big baby and who can the handle pressure.
It makes sense. Everyone situation is unique.
I'm dealing with some entitled person in my family so I have learnt to be defensive on this sort of requests. I'm prividing help but with the clear boundaries. I'm not going to sacrifice my life because someone wants to.
I don't know if that's obvious for people entering this profession but mind that you don't read code like a book. Check how the functions you use are implemented. What's being called from where (call stack helps in the debugger). How are experience programmers managing their code etc. It's a good skill to learn how to navigate other people code and quickly find the parts that matter
It might be silly but it works and it's legal (here). It saved me a lot of hassle. I didn't have to send a physical copy. It become a trash a moment after I scanned it
Not where I live. You either need a physical signature on a piece of paper (can be later scanned) or a "Qualified Electronic Signature" to go full digital. The latter costs money it's not universally supported - small business owners often have no idea how it works.
Those are the only two options that are legally recognised as valid signature
This is also the only reason why I have a printer.
Point 1 is pure speculation. You could say the same about any profession. Absolutely not something woth considering when looking for career opportunities. You can always pivot with your career and knowing how to code is a plus because that makes you understand tech better
Plastic fasteners on socks. They are too short to use scrisors and often damage socks if you don't. Too many times I ended up with damaged brand new socks because getting them out od that plastic trap is too hard for me.
I always choose socks held by cardboard only if available.
