Instead of not having a problem with something - why not say something more positive - like "I will look into that." (That's something I would consider certainly.) (Thanks - that's a good idea!) - watch out, that last one was almost optimistic!
I wouldn’t NOT go that event because…
I wouldn’t totally discount that possibility…
I hear it all day long.
Challenge for the Day - take a "careful" or possibly deemed negative statement - and turn it into something more decisive - and positive!
I dare ya! (I won't negate the possibility that you can't do it!)
