I had two meetings today.
In the first meeting, we had a couple different people presenting portions of a slide deck.  At one point I noticed one of the presenters was talking a little quickly.  Not so quickly that he seemed rushed, or that I couldn't understand - but fast enough so that a)I noticed it was a faster than normal pace and b)I didn't quite have time to read the slides being displayed on the screen because I was too busy listening.  Thus, while I got all the salient points of the presentation, I found myself wishing it was a little slower.
In the second meeting, I was giving a presentation to a small group of co-workers.  I don't give presentations very often.  I tried to be conscious of pacing and not rush my speech of ramble on.  A number of times I stopped for a moment to take a breath, and let everyone catch up or ask questions if they  needed to.  During these times, I found the silence rather awkward and felt compelled to jump right ahead with whatever came next.
I guess the best way to put yourself in someone else's shoes is to just go ahead and lace them up.
