Jacob joined Kayla in laughing, "In that case, as your brother I'm obligated to make this long trek with you...to keep you safe of course."  He paused to take another drink from his glass before pointing to Kayla's glass.  "You want me to warm up that milk for you?  Milk's always best hot at night in my opinion."  He held out his hand helpfully gesturing to Kayla's glass with a smile.  Jacob wanted to show that he was making the effort to make Kayla feel like they were always siblings.
