Honor her request.

You send her a text back immediately; “hey Tina, sorry my phone was charging. I haven’t opened your bag. I’ll just keep it in my closet until we meet up, and I promise I won’t peek inside.”

You lay down in bed, and she texts back; “thank you so much! You’re a total sweetheart!”

“It’s not crack, is it?”

She replies right away; “it’s actually meth ;)”

“Oooo let me have some! XD” you reply.

You text back and forth a bit, and eventually you agree to meet to hand off the bag on the following weekend. You just need to think of a place to meet up.
