> 1. Sometimes for no apparent reason, you'll start crying

Phew, for a minute there I thought I had an unknown child somewhere out there.

No, but to be fair it's a good warning. I was never one to really let my emotions out like that, but random crying for no apparent reason definitely became a thing for me for the first few months of my son's life. I didn't know what was going on until other fathers admitted it happened to them too. That made me so much more comfortable with it.

For some people it definitely does. I also got the habit of sitting in my car for half an hour once for a while, doing nothing and listening to music. It's miserable for the "right" person.

Kids will bring emotions out in you that you have locked away, for better or for worst.
