Ah, Anglo-Saxon work culture, where one can't imagine not making friends at work because they have no social life outside of work.

Not making friends at work because you have fulfilled social life already, and not making friends at work to avoid any danger to your career are two very different things.

Not making friends at work, because it's not a good place to make friends, might push you towards ensuring having fulfilled social life outside of work.

I say this without rancor: unless I miss my mark, you don't live or work in the United States. You don't understand the stakes. I envy your life brother; I hope you appreciate it.

I live and work in Europe but I used to travel a lot for work to the US. Friendship or making friends indeed seems to work differently there, which was hard to grasp from my cultural pov. That said, I made a good friend there.
