What do you do if you're asked to babysit?

My neighbors requested me to babysit their 10 year old daughter for tonight because they both have something urgent related to work

I never had a little sibling nor do I have any experience baby sitting.. I have no idea what to talk/ask or do LoL...

I am mainly confused about what to cook for the night , cause I am sure she would hate the usual boring meals I have haha (Healthy though)

Thanks for the opinions

Turns out her 7 year old brother just returned from Grandma's and he'll join too.. Hope I survive...
