Parakeet With Unclipped Wings?

Hello, I have had this parakeet for about a year. His name is Angel and he is extremely tame. His wings grew out and he can fly fully now. I was wondering if we should clip them. He's as sweet as can be. He'll fly to you, your head (his favorite place), your arm, and everything. Whenever he finds my two otherparakeets, or my two other atiels, he flies over to them and grooms them and plays a bird version of tag with them. He lands on safe places, and he doesn't poop on anyone. And whenever I say, "bed time," or "Night night," he flies into his cage and pulls the cover down by hisself! But he having trouble closing the door, lol. But my uncle is paralyzed and he has nurses came every week. And Angel being the friendly bird he is, flew on top of the nurse's head and started to groom her. The nurse threw Angel on the ground (which I didn't like at all! *grits teeth*) And said "You stupid bird! Your owner's really need to do something to your wings!" And Angel flew to me and hid in my hair, snugged really close to me. I felt really bad. Angel was just trying to be nice, he's an all-people bird. He flies to every body, and most of the the time they love it, and pet Angel saying, "Wow! This is such a friendly bird! She (people think he's a her, lol) is so nice!" And I feel all happy inside. Do you think I should clip them? He is the perfect bird, but I don't want people thinking he's trying to attack them when Angel's really making friends. What should I do? I really enjoy him, and my family loves to sit and watch what he does, fly on my dog's back, climb on my dad's head when he gets up, tries to talk to the birds on t.v., he's perfect, but I don't want anybody making a mistake with attacking and making friends. He never tries to go outside, but he does enjoy sitting by the window and chirping to the local birds. What do you think I should do? Clip them, or leave Angel the happy and increbly sweet flying bird he is? Please help. He's an Albino parakeet so he's unique in coloring, too.
