What does it mean if a guy friend shows up at your house unannounced?

Anonymous
I've been upset with him because of something he has done (I like him by the way). so for the past few days i've been making excuses when he asks to meet up. today I made an excuse and he said if he could just please see me for a few minutes to talk to me. I said no, i'm busy. He then just showed up to my house! started knocking on the door then texted that he's here.

What do I make of this? is it weird or does it mean he values my friendship? or does he like me? I don't get it?
