"Horrendous sum" is always relative. For a roll, 4 euros would already be a horrendous sum if it normally costs 50 cents. For a vacation, I personally find 1000 euros for 1-2 weeks economically totally nonsensical, and it regularly costs that much for 2 people - at least. When I think about what I can do better with 1000 euros... If I want to relax, I go to the garden. Traveling, in my feeling, is always only associated with stress (not just vacation, also other forced "trips"... you can see that nowadays with the chaos with trains and planes). It already annoys me when I have to visit family in my hometown again, that's 600 km one way and I try to avoid it as much as possible. But every 3-5 years it has to happen again.
As a child, I wouldn’t have needed a vacation either, small trips would have been enough. However, there weren’t any. Going to the zoo or to the sea (I lived on the coast), or to an amusement park or climbing. You don’t have to go to the South Seas for that. At our place, school vacations were spent in front of the TV. Without money, nothing else was possible in the big city. That has affected my current life mainly in that I absolutely dislike going anywhere (and then having to pay for it?). But on the other hand, I place the greatest value on my everyday life and my home being perfectly arranged according to my needs. In my opinion, you get more out of that than torturing yourself 48 weeks a year and then spending 4 weeks making a big fuss for a lot of money. The recovery then, as you can clearly see from others, unfortunately does not last very long either.
By the way, other acquaintances and relatives I have also never or hardly ever go on vacation. Only in the "media" do you then read in amazement that apparently vacation is standard for many people. Well, lifestyles can be so different.
Fortunately, my husband is no different in that respect. On the contrary, compared to him, I am still a travel enthusiast. On the few occasions when I "had to" go abroad, I took him with me. It was exhausting each time and without him I wouldn’t have endured it at all. But in hindsight, it was each time an experience that one somehow likes to remember - paradoxical!
