Let your kids know that as long as they
grow up to be good people, you don't have the final say in what they
become, but love and support them anyway.
My parents let me know that they loved me, no matter what path I
took, and even though I went to undergrad school for theatre, I got my
MBA and now have a great job. Friends took the opposite path (business
school first because their parents insisted) and ended up miserable and
are now thinking about changing careers.
We're using that with DD (my partner has the same philosophy) and
even though it's looking like we're going to have a queer daughter who
wants to be in the military, which is the last place she *should* want
to go all things considered, she knows we love her, support and respect
her decision, and want her to go Air Force or Navy like our respective
families have. :-)
