Never neglect someone whom is being true to you just to be "in" with the rest, because you never know until when that rest (crowd) is going to like you.
Husband/wife, neglecting your partner's feeling must be your greatest "no". Don't ever neglect his/her feelings just to make friends or relatives feel valuable. Valuing each others feelings will give you harmony and peace of living.
Parent (especially Mother) do not neglect your children's feelings. Don't care more on one and less on another. Don't give more on one and less on another just because he/she is more independent than the other. Always love your children fairly.
