It depends on the person and what they do and are like.
The main deciding factor is if they are family, e.g. recently born or recently married. If you are family I’ll die to defend you from day 1, thats the rule. If you are family you are automatically fully accepted and liked, and bonding becomes very easy, something that is done in minutes.
Another big deciding factor is if you smoke weed. I no longer smoke weed, however, if you do, there is a much greater chance that I’m going to like you, just because there are certain things I’m safe assuming about you. I know I can depend on you to hear “cops” any time they turn a corner, I know you are likely to be more peaceful, and I know you will be open to talking about more or less any topic, as well as being ok with sitting there with me for 6 hours in total silence.
The other big factor, is if there is mutual physical attraction, this always tends to move things on, probably because it tends to get me acting more honest.
