How do you guys feel when a female doesn't respond to your texts messages?

When I see, said female. I don't want to act butt hurt, so I obviously don't bring it up.

But that shit still irks me. When anybody does it.

Someone will bring up the argument that "people are busy". True and that's a valid reason.

But that shit still irks me,

So for those of you who have this same issue : how do you approach the situation, what actions do you take?
