Whether it's with my SO or friends, texts eventually get to the point where I think to myself "Okay, this a good stopping point. I asked them how my day was, and vice versa." If it gets to the point where I feel like my response is going to be a half-assed "Oh, that's cool." Or "Dang, that's shitty." I typically opt not to respond at at all, especially in the case of my SO when I know we are gonna see each other in a couple hours and I'll be able to get to the meat of the text they sent
 
I find it more difficult to determine when it's okay to just not respond, because I think everything's already been addressed in that format. Then I get messages like saying things like "did you see my text?" And it just sours the whole texting thing for me even more. I get it if it's something that needs a response and is time sensitive, but other than that I don't see the need to respond if I'm going to communicate with you face to face about in a few hours.
