I don't know how old your kid is, but my little girl is 2 in a few weeks and she sure as hell tests my limits.

I am a VERY laid-back person. I don't believe that kids exist purely to manipulate us, and I do believe that a lot of what some people think is "misbehaving" is just a kid's learning journey (exploring emotions, boundaries etc) but even so... wow. I've found patience I never knew I had.
