Tricked my boyfriend

So, I've been on and off using purple shampoo to help the tone of my hair. I had the shampoo in my hair and walked into my boyfriend’s home office and when he turned around my hair was lathered dark purple and I'm like, "so, I don't know how to tell you this, but I'm dying my hair purple, like right now." (Him used to me being platinum blonde for the past two years) His mouth just dropped open. "OH BABE I HOPE THIS IS TEMPORARY!" I don't say anything, just stare back at him grinning. He's shocked, eyes wide, stuttering. "It's temporary. Please tell me it's temporary. Oh God it's temporary." I just burst out laughing. The relief on his face when I washed it out 😂😂 lol
