One of the things I have a hard time conveying to non-parents is that the most time-intensive parts of parenting don't last forever. I've talked to a lot of young people who say they don't want kids because they think their personal lives will permanently halt the moment they have kids. I spend a lot of time trying to explain that: 1) I still spend a lot of time with friends and can do most of my personal hobbies/act…
When I imagine taking kids to the park, or camping or reading to them, or playing with them it just seems like a chore. Is that something that magically becomes different if it's _your_ kid? With my niece and nephew I enjoyed playing with them for an hour or so, then I wanted to be left alone. I get the feeling parenting is a bad idea in general for people who love being alone for extended periods of time.
It wasn't enjoyable from the get go. But with time we started forming a bond and having our own little habits.
Bottom line is initially you don't know this person so it's hard to expect from you to automatically have a great time. But as a child develops they become more interesting overall.
