Hey Eric,
The part I like most in your plot plan is the contrast between your quiet grandma and your loud Australian self. I think we can deepen this to become a very powerful metaphor. Obviously, you should adapt this to however you feel comfortable writing this. Perhaps you should stray from the complete truth of your experience in the name of a good story, but you should definitely drawn on your experiences to give a sense of authenticity.
Perhaps you could write about how you have to be loud and active to be noticed, valued, and important in the Australian setting. You're used to team mates congratulating each other to show their appreciation and support, it's all very vocal. But when you meet your grandmother, it's quiet, and you're quiet. At first this is unsettling and you feel it is awkward because you want to fill the space with noise, because it's what you know. Then, *plot continues*, you discover that even in the humbling quietness of your grandmother's presence, you are supported and loved and appreciated, like you are in basketball. It's just that grandma will show you in authentic ways, (simple things, making tea, burning candles to make the house smell nice, cooking in advance, whatever it may be), whereas at basketball the love is vocal. So you discover that neither of these situations are the
right way to show appreciation, but rather love and appreciation is a chameleon, it shows itself
differently and if you are willing to be open to new communication, you'll discover new landscapes of love, new emotions, and have a new perspective on the way love manifests.
Okay maybe I went a little overboard with the storyplan... but I think this incorporates lots of discovery boxes and if you bring in authentic descriptions and experiences with your grandma, the story will really come to life. I've changed your storyboard... please only follow through with whatever you feel is strong. But remember, don't just hit one discovery box, touch as many aspects of the rubric as you can without being vague on any.
Smells - you could definitely describe the basketball court as pungent, sweaty, stinky sweet, like deoderant...rubber from the ball even? A bit of everything. With your grandma, maybe everything smells fresh because she lives surrounded by plants, or sweet because she burns candles, or maybe aromatic because she makes curries or lives near a market.
Good luck
