This weeks BTT looked like a quick one:
"I’ve always wondered what other people do when they come across a word/phrase that they’ve never heard before. I mean, do they jot it down on paper so they can look it up later, or do they stop reading to look it up on the dictionary/google it or do they just continue reading and forget about the word?"
I do the following:
1) Figure it out from the text.
2) if I can't figure it out from the text, decide how far the computer/dictionary is from me
3) if the computer/dictionary is pretty close I'll google or look it up.
4) if the computer/dictionary is far I'll give up and keep reading. If I remember later about the word and happen to be near the computer/dictionary, I'll look it up, but this doesn't happen often because I'm forgetful.
Lazy. The end.
When I was a kid I'd just yell to my mom – "Mommm what does this word mean?" and then she would tell me to go look it up. Which was annoying. But I have to look things up a lot less now than then.

Yeah I'm too lazy to look it up.
heheh. I'm not alone.
I do the same thing… If the word keeps bothering me, then I'll actually look it up later, but I will usually forget. The way I see it, if it plagues me later on or pops up in everyday conversation, then it's fate telling me to look it up, but most times it simply fades into nothingness.
