Culture Shock/Dating Fail/Lazy Saturday

8 days ago friday night I was having an excellent time dancing with a beautiful-intelligent-sexy young woman, the kind of flirty dancing that I took to have intent to follow through, and so I suggested that I should take her out on a date some time and she said that sounded like a nice idea. I had given her my phone number and email address and she had texted me and I had texted her (I would have much rather emailed, more writing space, better UI, but I didn't have her email) and I think I was waiting for her to email me. Last night I discovered she was waiting for me to call her. It never occurred to me to use my phone to contact her at her phone number for voice communications. I just do do that. So I spent about the next two hours of the dance just kind of dumfounded in shock that my brain had not processed something so basic, that yet still felt so strange to me. She said she had something to do Saturday, so maybe I'll call Sunday and see about scheduling something for next week/weekend. ... if I'm not still too dumb and foolish feeling to be able to make a serious go of it.

Now I have a totally unscheduled Saturday, and even before last night's shock I was feeling a great ennui towards today. It probably means I need more rest after a hard work week, so I will try to really rest until I figure out if there's something I really want to do.

Word choice

Apparently at some point I started assuming I was done learning the English language. I think I'm pretty well educated and have a pretty good grasp of the language as it is used these days. Now at least half the time I hear a word I don't know I question the judgement of the user of that word. Are they trying to sound uppity by using an obscure word? Why can't they use something more plain so that they'd be more widely understood? Does that obscure word really have anything that the common ones don't?
