How prevalent alcohol culture is in the West. I’m Southeast Asian and it’s more common for us to drink sugary drinks and have food at the local corner restaurant at night instead of having alcohol when we spend time with friends.
When I studied in the West, it really struck me how the only place you really could hang out at night was the bar, and alcohol was often the preferred drink. And they normally closed at 12am, so you can’t even stay out that late.
Personally I’m not very fond of inebriation just due to the issues it creates (not that my friends were alcoholics and got blackout drunk every time we hung out), so I found it kind of bad that it’s so socially accepted to see a need to get drunk in order to tolerate socialising with friends.
I think it’s definitely really early to say if they have proper romantic interest in you, given you’ve only known each other about a week? But from your post, it seems like you two have points in common and have a lot to chat about, which is often a good foundation for relationships, friendly and romantic.
In terms of learning Linux, it’s probably ideal to have a bit more of an outline of what you want to start teaching her because it’s a huge jump into a new OS (not that I know much of myself). She may not know where to ask you to start and would appreciate more suggestions from you on where to begin, like telling her “Today, let me show you (practically) how to install (OS) on a system and navigate it” and going off that.
I think the tl;dr would be: Have a Linux lesson plan, expect friendship first. Take it slow.
Hope things go well.
