I think ISFJs may most like to do things for people. Whether or not that is pleasing to them is perhaps another question.
I don't mean this in any manner of disrespect. ISFJs are wonderful, unselfish, loyal and caring - so much so, they can be taken for granted.
I would have thought the answer may be some type of NF but am not sure which.
Yeah, it's absolutely not in a condescending way that I say ISFJs either....
and I've known NFPs who like to people-please or have trouble saying "no", but FPs may have more of a rebellious streak.
I know an iNFP woman who is probably an e9 and she has said she wishes she wasn't such a people-pleaser.
However, I see ISFJs being much more consistent in displaying and acting on a sense of duty to others. Maybe it's just cuz I see myself as a bit self-absorbed (e4 after all), I avoid responsibility for tasks, and "no" comes pretty easily to me in most situations. ISxJs in general seem to really enjoy making other people happy, and I think many like to feel needed, just as I like to feel unique.

I agree with ISFJs too. I actually know a couple of ISFJs who both will be *so nice* that they practically sacrifice their own wants/needs. It's like they both value being nice and pleasing other people more than they value being true to themselves. I suppose if their morality is founded off of pleasing others, then they are indeed being true to themselves, in some sense, but I'm still not sure that they're compassionate actions are always the best decisions regarding their own mental/emotional health. But they're nice and I truly adore my ISFJ friends
Anyway, yeah. ISFJs to the max.
Oh and I agree with BarberElla about being genuine. I think compassion from an ISFJ is founded on the utmost sincerity.
I'll agree with everyone too. I dated one. She's always letting her friends know she can't wait to see them again, thanking them for stuff online other people just move on about, etc. But it's in a genuine way without being a doormat. Although now if I see her I have to acknowledge her first or else no communication takes place. But that's probably because we've slipped back to being acquaintances and are going in different life directions.
