Re: "You're making us nervous."
You should have just told her you didn't have any gummi bears.
I can see why she would be a bit apprehensive, but to actually come up to you is out of line and not very smart. It's a public park for one, so you have every right to use it's space legally. Second, if I think someone is possibly up to no good, the last thing I'm going to do is approach them.
