If you think it is ok, even desirable, to show up early when meeting someone at their house, why do you think that is a good thing?
Whether you are going there to hang out, or going there to pick someone up, why would you show up early? How early do you think is ok? Does it matter who you are meeting, or why you are meeting whether you show up early?
I also wonder if people who think it is ok, also think it is rude when people are late, or are ok when someone is a little tardy.
