Dirty talk (on occasion - not all the time) and regular conversation, whenever I check it (very often, normally as often as I check my phone), the responses (it varies)
I love kik - I consider my members friends. I kik them as often as I would text, so with some people we kik all the time. Random stuff, my plans, their plans, how work went, scandalous pictures, etc. Other people, not so much. My favorite core group of regulars hear from me all the time, I would say I talk to them and reply extremely quickly. The dude who told me I was fat and it's holding me back? He probably won't hear from me too much until I stop being a brat and reply.
Basically I treat it just like friends: if you we get along you're going to hear from me often.
