My h. can be (engineer-like) a bit of a bubble burster, too. Confronted with a new idea, his natural instinct, honed from years of hard work, is to find the fail points. This is VERY IRRITATING to a person who is just dream-spinning or fantasizing idly, as in, "Wouldn't it be fun if????" If you do this a lot, you might wanna consider thinking before you speak. Best-case-scenario dreaming can be really enjoyable with your partner. Who doesn't like to dream with their loved one, even if they know the reality is unlikely?
OK. I am an engineer and did the bubble-bursting way too much before. But I think I have piped it down quite a bit in the last year or so.
