I think most ppl are fine with it if it is only once and you seem genuinely sad about it. I am fine with ppl forgetting we even met I am even playing along pretending it is the first time we meet, so far has it only been ppl I met maybe twice in my life(except one person). I have only met one person who actually got sad when I forgot her name. She asked if I was not as happy as she was to see me.. That hurt, I remembered her tho! But not her name.
I think it is worse when I have to introduce myself everytime we meet and it has been over 3 times... One dude he never remembered me until the 5th time then he said "heey we have met before right?! " he even looked genuinely happy and I felt "finally we can stop pretending" but then the next time we met he introduced him self again... I remember you Felix!
I have always wondered what advance is when ppl say Linux is difficult when you have to do something advance. Isn't that the same for all oses? A os no matter what os (mac, android, Windows, iOS, linux) is difficult to use the first time. It doesn't matter witch os it is everyone will have a hard time the first time until they learn how it works. Mac for example, it was extremely hard for me to find how to get to my root folder without using the terminal and when I told a friend about it who use mac didn't they know either... I found out by accidently by miss clicking. Android depending on brand (what you had before) can also be annoying to use the first week or weeks until you have relearned.
Linux is the same, it isn't more advance than windows or Mac the first time, it is all about learning how it works (most ppl build their Ikea furniture first and then read the manual) and windows and Linux in that regard is at least kinda similar because they don't hide stuff as mac os does (you still ned a lot of knowledge to use windows too) and they are kinda alike, Mac is completely backwards in my opinion. I think everyone forgets how it was the first year they used a computer for the first time. Ppl laugh when studies shows that the younger generation do not know or do not understand the folder structure. It is all about experience and knowledge, if you know something exist then it is easier to find it.
The biggest problem i had using Linux for the first time was finding good alternatives for programs. And learning these new programs. You don't have to use a terminal with most distros now days but it is a very nice and fast interface to use. It is also easier for everyone to learn and use because it is less dependent on what kind of environment you are in.
But I think we both are kinda agreeing with each other I just want to point out that all os are difficult the first time and you don't have to make it harder than it is, linux is beginner friendly just like any other os.
