We just road tripped (1500 miles) our firstborn to college. If I remember correctly (and believe me, I will write the part of Me much better in my autopseudobiography), what she wanted to be when she grew up was, "taller than Mommy." (We quit asking that question.) Good job, Princess. Now, go do that at college.
Daughter in the Middle's early elementary (Isn't this the group traditionally known and appreciated for their capacity for over the top, tritely praiseful, to the point of occasionally blatantly untrue, sentiments in the pursuit of declaring their love for, and attempting to garner the favor of, the adults most present in their lives?) Mother's Day project for, and about, me included the phrase, "and a pinch of mean." Honesty is a family value that, when taught early and well, will end up teaching you a thing or two back. Probably two.
Baby's earliest voiced career aspirations ("Awww." Silently congratulates self. "My baby admires me so much she wants to be just like me. I must be pretty great after all.") turned out to be based entirely on a desire to "sleep all day," which is a real option for grave shift healthcare workers, but not so much for traditional teachers, librarians, etc.
Maybe a good family is just bad enough to make adult kids want to leave, and/or just good enough to make those same adult children want to come back and visit later.
