"Talking out of Turn"

I listened to Long Distance Voyager yester-day and noticed a few things.  In "Talking out of Turn," there are guitar glissandi after the lines "Let you slip through my fingers" and "Let you escape like yesterday" (I think each is a B held for a beat or two and then slid down the string).  Musically, this represents the "slip[ping]" and "escap[ing]."
