If you come across an unfamiliar word, do you stop and look it up right away?
No. No, I don't. I very rarely come across words that I'm not at least a bit familiar with but when I do, I try to figure out the meaning from the context in which it is used. That usually works. Then I think to myself: "Why in the world did the author feel the need to use a word like that?" Totally unnecessary.
It kinda bugs me and I don't want to waste more reading time by looking it up. Mostly because I'm usually either outside reading or nice and comfy in my bed and it would just be a bother.
