Points where to be careful

4 pays exceptional attention to what he is missing, and with time, can become more demanding and critical towards 9. 9 gives unconditional acceptance to 4 and expects it in return. 4 wants excitement and intensity, while 9 wants comfort. This is causes a conflicting problem. 4 can be dissatisfied with how relaxed the relationship is, and disappoint 9 who will close in on himself.
9 can perceive 4 as being too demanding, selfish, critical, dramatic and emotionally unstable.
4 can perceive 9 as being too disorganised, lazy, irresponsible, inefficient, boring and stubborn.
