Opinions should be paid attention if you wish to keep the relationship. Not putting one's partner's opinion into consideration make them feel unimportant or unreasonable and that's why opinions should not always be disregarded. If there's a reason you think your partner's opinion won't work out, then you should probably talk about it and make sure your partner is convinced by your reasons.

I for one like to hear and put people's opinions in mind. No man knows all and it's not possible for all of us to see things in one perspective. 0.5 from A, 0.3 from B, 0.2 from C, all will sum up to 1-that's bigger than what they all could have given individually. Listen to that guy beside you, he might be saying something reasonable, you never can tell.

Let me drop my pen now...
