Input: Text: so today my grandmother decided to do my laundry. no big deal as i normally don't leave anything in my pockets that can't be washed. well today i royally fucked up by leaving my bag of weed in my pocket. (my family is neutral toward the devil's weed, so i knew i wouldn't get in trouble.) but long story short, in her effort to be nice, my grandma washed my bag of weed.
