In response to the ISTP/INFP thread
I find ISFP quite refreshing. They are very nice and I have a lot of fun around them typically. The only problem I seem to have is that I feel like they can't keep up mentally. They usually don't seem to understand what I'm talking about. They make an effort and try to understand but are often unable to contribute. In order to really communicate I find myself making a lot of sarcastic jokes, and they just seem to laugh and smile at almost everything I say. I often feel like I'm not really getting through to them, but they still seem to enjoy my presence.
Often times when they are talking about something I have little to say as well. Usually they'll talk about something they did in which cases i often find it funny. Almost like they purposefully put themselves into predicaments that could have easily been avoided. They seem to be aware of this though.
Overall I enjoy the company of ISFPs. I feel comfortable in their presence, but often feel like we speak different languages since we have little to say about what the other speaks of. Funny thing is that we always have something to say regardless of this enigma. Kinda like we are both talking at each other rather than to each other.
