Anyway, it reminded me again about the reason why I don't typically use chinaware (or metalware) if I don't have to do so. Although some cockatiels can imitate words, my little guy only imitates sounds: microwave beeps (I swear I can cook without it), my laugh, kissy sounds, but the one that sticks out most in my mind is when he imitates the sound of metal scraping against plastic (usually at the same time I'm scraping the last bit of ice cream from my Tupperware bowl.) If it weren't for my realizing several years ago what he was trying to imitate with that last sound, I might not have been able to make the connection that the reason why I've used plasticware instead of metal silverware and chinaware over the past two decades is because my body subconsciously wanted to avoid the "clinking" sound of metal on china that's one of my triggers.
I guess I should feel lucky that only one of the sounds he makes is a trigger for me. The rest of them just make me laugh - especially when he imitates my laugh and we wind up laughing at each other. :-)
