Oh, you're poor nose! Yes, I have been there too. I'm also guessing Merlin wanted his ball. Their noggins are so big and thick he probably didn't feel a thing. I think he was trying to understand why you're swatting at little birds flying around your head, rather than tossing his ball to him.
If it's any consolation, Sierra swept me off my feet last night and NOT in the good way! We were outside adding on to our pool deck and she started to wander a little too far into the woods, so I called her to me. Good news is, she came as soon as I called (YAY!!!). Bad news is, she failed to notice I was right in her line of fire. Normally she comes barreling down at you and veers off to the side right before she gets to you, so I didn't move. Well, she must have forgotten to swerve because she plowed right into my knee at top speed, hyper-extending it. I thought she broke my leg. I flipped over her and landed on my face in the dirt. Needless to say I was done helping with the deck.
