D'you ever have something really worthwhile to mention, and then the moment you get a chance to speak, you forget all about it? What do you make of it?

I'm looking at 80 yrs old..I take it as an old man condition..  Usually it'll resurface at a later time..

I'm more than fifty years younger than you and I have this problem. D'ya think it's the weed, or the totally-disengaged summer-brain? 

No, 'cause I always just interrupt everyone every time I have something to say. 

I did it much less 50 years ago and recovered more quickly..   Could be as you suggest..although I've seen many kids (no weed involved) do the same thing..

lose one's train of thought

Fig. to forget what one was talking or thinking about...

Hey, nice one. I do that sometimes, too. Is that workin' pretty well for ya? Are you gettin' what you're after? 

Hehe thanks for the clarification, Beans. You're a true pal.
