[Touches his shoulder gently, squeezing.] Everyone goes at their own pace. It's okay if you're not up for that yet. But for what it's worth-- nothing about you has ever indicated to me that you'd be bad at it. You never do anything by half-measures.
[Hang ups or otherwise, he is fully on the train of "Keith would be an excellent boyfriend" and it makes his heart hurt a little but anyway.]
But anyway... [Pats his shoulder.] Last thing you need is me being condescending about dating.
