I most definitely agree with Angelene - you are overanalyzing.

I had to read the post twice because on first reading, I could not even get a faintest idea of what the subject of an apology could be.

Your hair and his touching it is the only thing that stands out. Not necessarily in a bad way, but just that - unusual. The rest seems like a normal exchange between two people who feel a little awkward in a situation in which feeling a little awkward is perfectly acceptable.

So your hair - is it very long?
