Get Back or else..

I left my camera at home so when I went to the lake and saw the swan family coming to shore I tried to get closer to the water’s  edge to get a good photo with my phone.  I didn’t even get that close when swan no.1 came out with a lowered head and headed right for me. I backed up a little but s/he continued to come towards me.  I turned away at that point  and left.
