Well, I use the word emergency kinda loosely; I just mean I want to be available if someone needs help. Like one time a friend's car broke down driving back from a party and he texted me around 2am, well past my bedtime, to see if I was still up to help. He would've called an uber and dealt with it in the morning if I hadn't responded, since he didn't want to wake me up, but I was happy to help anyway, so I just pretended that I'd been awake to keep him from feeling bad.
