When you role play with another role player and something important to the characters happen, but the next day they speak nothing of it/does something to contrast it.

Ex.

*Roleplayer 1*: Will you be my girlfriend..?

*Roleplayer 2*: Yes (Blah blah blah sappy stuff)
~Next Day~

*Roleplayer 1*: Hey! Guess what I got a date tonight!
