They go to sleep

Esther: well let's think about whether or not we are going to do this. The invitation is for tomorrow. So we could call them tomorrow or not.

Jennifer: well we don't have any other plans tomorrow why wouldn't we do it.

Esther: yeah I guess... But it is kind of sketchy. We don't know who send this to us. There are a lot of strange people around this world, what if there is some crazy **** behind this....

Jennifer: well let's just call them and see what kind of message it says on the phone.

They just go to sleep...

When they wake up the next morning. They decide to call the number to check out what it says...
