speech bubbles?

[pinkwave]

Hi guys What does a red line through the speech bubble mean when two Sims are talking? I mean the actual prompt thingy. For instance "compliment home" would have a red line through it?? I've searched everywhere for an answer and I can't find one. All I can find is questions on how to remove them. Maybe because this is a dumb question?

Thanks in advance.

It could be that your Sim is unable to perform that particular action due to their traits.

Oh ok thanks, yeah that makes sense sort of? Why not just leave it out though? Well I guess it's a good idea. You realize the traits of the person you're playing. I'm playing grumpy Agnes, so I guess she can't make too many compliments
