Remember an occasion when you needed a gift for someone special. How hard did you look? Where did you find it? Did you give them something store-bought or something from your home?
Recall the thought process that went into the choosing. How long did you think about it? How hard did you research? What was your final decision? How did this make you feel?
At some time your character will need to buy a gift for someone. Does your character have the money to buy the gift he wants? If not, how much is he willing to sacrifice in order to get it?
Write the story that tells of the emotions that run through his head as he goes through the process. Make sure that the reader feels the turmoil, the confusion, the decision-making process that takes place.
Have fun with this one.
