Freeze in fear. The whole Jurassic park thing would come to mind. "They can't see you if you don't move"

Hide and call the police immediately, and text people I know, without making any sound ofc

baragade myself and my family in the bathroom - climb out of that window while dialling the police! Then drive off to safety

Maybe offer them some food

They wouldn't dare.. I have guard dogs

Close range combat don't let me down!

Hug him

Ask him/her to buy me gummy bears

jump through the nearest window

Get my gun, tell them to leave immediately and the rest is up to them.

Well with my training and my background probably kill it
