My mom is an ISTP and I'm an ENFJ. Growing up, I always felt like she lacked passion and didn't provide any structure as a parent. I was verbally critical of her when I was a teenager.
She isn't affectionate, and I'm often hugging her and sitting near her (to her annoyance). We have an excellent relationship, though. It's hard to explain. I respect her very much - I see her as wise, independent, hard-working, tolerant. I think she sees me as emotional, loving, affectionate, creative...but probably a bit too chatty and maybe over-the-top with my ideas and desire to chat.
We have disagreements when she is stubborn about doing things her way, and I seek change and improvement (i.e. I want her to be more physically active and try to get her to exercise with me, and she tends to become defensive and annoyed by the pressure I put on her to improve her current well-being.)
She also doesn't like it when I cry. Especially when it's about the same thing more than once.
She's a database designer (computer programmer). I'm a dentist. We both are very good at what we do, but tend not to understand each other's work.
She's a great mom, but tough to have as a mom when you're Fe. Love her though.
