I really hope this is toothpaste

So we had a friend of my partners stay over the other night. We decided to pull an all nighter as had to get him to the coach station at 5am and he asked to use our shower. Thankfully I had stocked the bathroom with fresh clean towels before he arrived. On our return from the coach station I went to do my morning routine in the bathroom and saw this on the towel!!! I don't remember him taking a toothbrush into the bathroom đŸ˜¯
