I don't like doing 1x1s with strangers, I tried to do it, it failed. I prefer doing it with someone I've RPed with before. 

You may be wondering, how that's different from RPing with a group of strangers? It is different. 1x1s are much more intimate. I prefer doing that with someone who knows my RPing style, and knows how to work with me. As well as vice versa.
