Just before Eileen goes to bed at $11$:$30$ p$.$m$.,$ she realizes that she forgot to confirm a meeting she is supposed to attend the following day. She texts her colleague the following message: $"$Hi$,$ it's Eileen. Are we still meeting tomorrow at $5$:$00?"$ What should she have done differently?

not bothered to include her name in the message

included a frowning face emoticon to apologize for forgetting.

taken an expensive Uber ride to pound on the colleague's door

waited to send the text right after she arrived at the office the next day

turned off her sound alerts so she will not be awakened if her colleague answers
