If you found out you were an adopted child (or if you are), would you (or did you) seek out your birth parents? Why or why not?

This question was inspired by @JLeslie’s question regarding whether you’d have a biological baby or adopt.

I’m just curious—would you (or did you) seek out your birth parents? Why or why not?

How would you feel if your adopted child wanted to meet his/her birth parents?
