At the start of your date ask your partner to come up with a random word. It can be as long or as short as they desire. Using the following list (or make up your own) take the word and assign each letter of the word to an item on the list. Do not change the order of the word or the items to keep it spontaneous! Then, come up with a way to fulfill each item that begins with the letter you assigned to it. For example if you partner came up with the word "tomato" you could wear (T) tunic's on your date or wear teal colored clothes. You could eat at a restaurant that starts with the letter "O" or eat something that starts with that letter. If the word your partner comes up with is longer or shorter than your list you could repeat an activity or take something out.
T O M A T O
What to wear? "T"
Eat at a restaurant or make your own food "O"
Visit a place "M"
Conversational topics "T"
From The Other Half,
Luckily I didn't go with my first word choice of 'antidisestablishmentarianism'. That would have been a really expensive date!
