tina: i can't be your friend because i saw a disturbing photo of you on social media. you were in a group photo with a person whose opinions i abhor. dilbert: can you explain why that makes me a bad person? tina: sure. duh. when you appear in photos with other people, you acquire their bad characteristics. dilbert: i don't think that's how it works. tina: that's exactly how it works! one photo with a jerk makes you a jerk! case closed! dilbert taking selfie with Tina in background: smile. tina upset: no-ooo!!!
