Why did he ignore the dare?

So my friend had a little party outing today, and we went to dinner and then bowling. On our way to bowling we invited our friend who is two years younger, and he joined us there. After, I mentioned them coming over to watch a movie, and everyone agreed. Once we got to my house, someone came up with the idea of playing truth or dare. Now, first of all, my friend likes this kid very much. So, one, I keep my distance because he can get touchy, and, two, I don’t like him at all ( in that way), so naturally if he does get touchy, I walk away to send a message. Anyway, back to truth or dare, I get one to kiss the person to my left on the cheek. As it happens, it turns out to be him, and I hesitated, thinking that “why not, what does a kiss on the cheek matter?” I then proceeded to say, ” it’s up to (guy’s name).” He was on his phone at the time before the question was asked and my friend mentioned he probably didn’t hear it. He then answered back that he did, and then said nothing. We just moved on to another question after that. I don’t know what it is, but I sort of feel awkward and somewhat insecure. It’s frustrating me to no end. He wasn’t awkward with me and talked to me the rest of the night, but he was also really distracted on his phone. What do you guys think he meant by just skipping over the dare? ( Also, he kept suggesting to play “dirty” truth or dare, so that also lead me to make my decision, as I deduced he was in favor of the dare).
