Well when you do a favor to someone. That person is usualy there for you. Ex: my friend nead help with someting if i help him he will tell me every thing about that thing i nead to do.
So i think it would be a greate idea when we do a favor to someone that he/she should help us 100% and work exactly like a contact. Sinse well we are doing a favor for that person. Common sense would be to never rule bending or other things. He nead our help so he nead to help...
Yeah, it's a bit of a ugly duckling. I can make the switch easy enough, the reason I'm hesitant is I'm not sure if it will make favors significantly easier. I suppose in most cases, the difference will be slight.
