I thought of this when I heard the phrase and capitalized a letter.
Explanation: "Have a little faith" is a phrase meaning you should have confidence, at least a little. However, Faith is also a female name, so if you need someone to babysit your kid and she's named Faith you can use this comic interaction as a template.
Text:
U: I don't know if I'm up for babysitting.
D: It'll be fine - have a little Faith.
F: Yay!
