What are spontaneuous things to do

If I would tell you, they would not be spontaneous anymore.

Seriously spontaneous thing is something that spurs into your mind unexpectedly.
It's automatic and drives from the within. It is something that you do without someone telling to do it and without it being part of your routine.

Spontaneous is something you do without planning it beforehand. It happens out of the heat of the moment. Effortlessly.

For example. You have planned a route and on the way come to a beautiful scenery and decide to take a short walk just enjoying the moment. The pause on your journey was not planned, it occurred when the option presented itself.

Or perhaps there is a party, and someone decides to give a speech. He starts speaking, out of his heart, having not planned it ahead.

Or a little boy (a toddler) kisses a girl of same age. Something surprising and natural.

Usually spontaneous things are nice things, fun things or irrational things. They always sprung out of emotion.

But there is always a dark side to this, some people have the tendency to spontaneous violence, which is always unprovoked. This is not the same as automatic reaction to a provocation. Reaction is always, a reaction and thus is not spontaneous.
