The best kind a friend is the one you could sit on a porch什么

The best kind a friend is the one you could sit on a porch,swing with,never say a word,and then walk away feeling like that was the best conversation you've had.：
世上最好的朋友是可以默默地陪著你,甚麽也不用说．然而,当他 离开时,你却会怀念和他一起的时光；
porch是门廊的意思,文中说到朋友是同你一起坐在门廊前默默地打秋千,意味着默默滴陪着你~
