Here is an illustrative anecdote since we are trading those:

I miss free housing, social justice, positive constrictive ideology, bearable work relations (or would it be more proper to say conditions?).

Age is…far above 30.

I admit, I haven’t encountered social justice or ideology in my very early ages, but I had opportunity to feel benefits of free housing (since my family got a nice 3bd-room flat in their possession), and…my parents worked much less than I do, and never worked at home.
