1) What is your enneagram core type and tritype?
I think I'm 7, if not 7 then 2. I'd assume both belong to my tritype. No idea of the rest.
2) If you had to be an enneagram type other than your own, which would it be? (You must choose a core other than your own, but you can pick the wing if you'd like.)
2w3
3) If you could imagine an ideal SO, what enneagram type would he or she be?
Someone passionate, intense, mentally quick and open-minded. If not my own type then maybe 8w7 or 6w7.
4) If you had to have one child, and you could choose his/her enneagram type, what would it be?
Someone to have awesome time with!

Well, if I indeed can choose, let's say
2,
6,
7, 8 or
9 then.
In both questions 3) and 4) I'd be less inclined to choose types 1, 3, 4, 5. 1s are rarely satisfied with things and I hate negativity. 3s seem way too work and result oriented to make a happy match with me. 4s are also too negative for me. 5s are not even nearly expressive enough to satisfy me. I might add to this list also 6s because of the pessimism and 9s because of the lack of passion. Very stereotype oriented approach here.
