The quickest way to learn someone's whole personality. No overthinking allowed — just gut instinct.
Coffee or tea? Beach or mountains? Morning person or night owl? Text or call? Sweet or savory?
Plan everything or go with the flow? Big party or close friends? City or countryside? Books or movies?
Time travel to the past or future? Read minds or teleport? Never be late or never be tired again?
This-or-that is even better with a stranger — instant chemistry, zero awkward silence. Give it a go.
