While walking on the beach with DH and our own dog, (which was on a lead at that time) I was aware of this crazy spaniel who was charging all over the place (as spaniels tend to do), he'd already been up and greeted our dog but they didn't have a proper play as ours was then on the lead because we were getting near to the beach's exit. A few minutes later I all of a sudden felt a huge blow to the back of my knees, I just fell to the ground in a heap. The crazy spaniel then stood over me trying to lick my face. DH was trying to pull me up but I literally just couldn't move straight away. Anyway the spaniels owner came along saying sorry but laughing at the same time.
I really didn't think it was funny, DH thought I was exaggerating with my inability to get straight up,
