Funny my ESFJ friend tells me she's really boring sometimes. She is a lot of fun actually, but in a very planned and structured way. But if I plan something last minute she NEVER comes, despite the fact we've been friends all our lives. If she has a spot in her schedule open and I book her in advance, she'll come.
We had a conversation about this last week about this contrasting nature between us. I told her I rarely know my weekend plans until Friday or actual day. If someone else doesn't plan something I'll call up friends and we'll do something. It never fails me. She has a lot of her life booked two months in advance.
And yet we both have very active social lives. Both methods produce the same result. Though her desire to plan everything also means she misses out on a lot of fun. And my last minute plans don't always work 100% the way I want them to.
