Well, that's merely one small example, IMO. Given @NIHM 's post echoed one I posted a few pages back, I'd say she meant more deep rooted issues than forgetfulness...Such as, as serenity stated, selfishness and/or narcissism. If your forgetfulness causes you to forget things rather important to an SO...sure, training yourself to take notes and keep a Calendar would be the right thing to do and not doing so would be selfish. But, more deep rooted than that, typically.In other words, human faults that were not worked on like forgetfulness?
The point I made and make again is people are too hung up on these 4 letters. They are how we see and process information and while there are commonalities within types, who a person is...which is what you fall in live with, has very little to do with how they process information and much to do with how they feel about various things at their core. What their values and character are, and their moral fiber...these are not type dependent. If I had a dollar for every post I've seen with "never thought I'd fall for that type" or similar, I'd be rich.
Hell, @ai.tran.75 even stated she never thought she would date her husband's type(ISTP?) but is more in love than ever.
I posted on this in an INFJ/ISTP relationship thread with very similar points and positive reception from the long time users because...it's true. MBTI can be helpful in that it helps you understand the functions of a person so that you don't misjudge reactions or reasons behind them. It shouldn't be used to assume you'll know who they are or how you'll feel about them. That's silly, IMO.
Ever hear the term used and echoed time and again "She/He is everything I never knew I always wanted". Judge how people make you feel based on who they are...not what four letters they carry for MBTI because, that expression often rings true, and for a reason. Doing otherwise may be selling yourself very short, IMO.
FYI, so I don't get a snarky or pissy response...I'm just putting my thoughts on this out there and not slighting anyone's intelligence.
