Ineffective ultimatum

Overheard in an airport concourse last week:

Mother to squalling child: "Do you want me to send you to your room?"

Dyslexia or just moment of doubt?

I always have to stop and think before I say or write these things:

• dot your i's and cross your t's
• move a date up or back (I just never say this because I'm not confident I use it the same way as everyone else)
• judgement or judgment
• Meán Fómhair or Deireadh Fómhair
• Daylight savings time or standard time
• cynical or sarcastic

Does anyone else have ones like this?
