My reasons to become a toy were... well, way more deep, psychological and metaphorical...
It took me a long 4-5 years to make connections, reflexions, and analysis as I wasn't even in the fandom, but only observing it. I developed with time a whole way of thinking of comparing my life with a balloonie. I mean, I prefer playing to working, floating free instead of being stuck and crushed/imprisoned, I always accumulate pressure by procrastinating, I want to make others happy, also be loved and taken care of, I do feel weak and inoffensive (more in the way I'm kind and don't want to hurt anyone) I thrust my friends and need them to hold me whenever I'm getting carried away, panic or am depressing, I'm dependent, easily following others i like being with as going alone my own way is hard, holding to the string of life with my friends instead of giving up, keeping hope, rising up every time i fall, always wanting to stay happy and positive the most i can... That's all both me, IRL and Balloon mouse. Metaphorically and symbolically. This is why I was a toy before even meeting you, Trask. 0w0
