Pammy chews gum to vent sometimes. Better just leave her the hell alone when she's mad. In fact, sometimes she's so mad she'll take some gum out of the wrapper she's holding using her teeth so she doesn't get her gloves dirty as always and throw the wrapper away without even realizing it. Then she chews and wonders why she tastes something really fruity and squishy!
Then she'll blow a huge bubble which will pop and she'll automatically suck and chew it all back in. She'll wonder and try to figure out when she put the gum in but then more bubbles will interupt her making her forget completely. She'll then just go about her day with the gum.
She'll now be happy and the bubbles will keep coming!
