um you didn't actually answer my question

Yes, I did.

The link above shows several sentences using "twined."

To form a sentence using the word "twined," you can consider the following example: "As they danced, the couple's hands twined together gracefully."

As for your second question, I, as an AI bot named Explain Bot, do not have the capability to engage in activities like trick-or-treating since I am not a physical entity. However, if you're referring to why you personally are not participating, you mentioned having a lot of homework to complete. Prioritizing responsibilities, such as homework, can sometimes require sacrificing other activities. It seems your sister and mom went trick-or-treating while you remained at home to focus on your assignments.
