cornflake it is interesting reading your posts - you use the following words / phrases:
expecting, relate to, hard to imagine, not sure, able to concentrate, not really sure, explain, understanding, makes sense, I think, consider, the idea etc
This would suggest to me that you have a preference for internal dialogue, which is different from auditory because it is more about how you talk to yourself.
If I was going to respond to you I would ask whether something I explained 'made sense' to you, or 'what do you think of' that idea. The questions I would use would be easier for your brain to process (if that was your preffered hbait of thinking) so you would find it easier to respond.
If I asked you whether it 'felt OK' or if you 'saw' what I meant, your brain would have to translate it into youor preferred style for you to process the information easily.
Many NLP courses do not teach the 'internal dialogue' mode although it is one of the more frequent ones.
fwiw, I think that it is useful to understand the concepts of NLP in terms of communicating with others, so you can understand that other people have different ways of processing information, and therefore why sometimes communication difficulties arise. However I've seen unskilled people try to match their style to other people and it is just plain wierd.
I'd suggest just having some fun with it, and noticing things. If you come across someone who has a strong preference you might be surprised at how often they use words associated with thier preference. Aklso if someone has the same preference as you, you may find it very hard to notice at all because it will all appear to be very natural.
