I'm not sure if this is what you mean, but in general I prefer a certain amount of predictability within my relationships. I tend/need to be relatively independent and I can feel bored rather quickly so I do welcome variety, but not as much spontaneity.
On the one hand you have excitement, on the other dependability.. I say put your hands together.
all is good in moderation, the idea is to find a good balance in my opinion.
Then again I'm assuming you are asking for pros and cons for the reasons of picking one or the other..
A person should strive to do a bit of both, life will kick you hard if you go with Spontaneous actions too often.. and letting life become too predictable takes away all its fun. just have to find whats right for you.
I need both in a positive way. I need to have spontenaity with another person, but at the same time I have to have a "bubble" in a sense of things I can predict within that spontenaity.
When I hear the word spontenious in regards to relationships, my brain often goes to unreliable. A corrallary, but not a garuntee.
I suppose that depends on who you ask. Predictability and spontaneity are death to one's relationship while life to another's, so it's all relative; but in general, I agree with Bird's post. Also, it really depends on what's predictable or spontaneous. Ex. Is recklessness involved or is the spontaneity primarily marked by suddenness?
...agreed with everyone, as far as pros and cons are concerned. They have its good and bad. I guess when it comes to relationships, I -think- I am the spontaneous (with high tendencies to go predictable) one. So...predictable. Hopefully not boring.
Not that the spontaneous isn't fun; but yeah, too much cook ruins the dish. Meh, preferably somewhere in the middle.
