allow for decompression, NO PARTIES, NO RELEATIVES, no mass get togethers, no we gotta go here, gotta go there, No we gotta go to dinner, NO any of that mess. Dont plan, dont coerce, dont obligate, dont tell other people when he is coming, or invite them over on his behalf. Dont make or agree to any plans or allow others to do the same. Dont know how to convey this strongly enough. If he wants to go out , or have get togethers let him do that. Nothing sucks more than being gone from home a year, get hime and all you want to do is BE HOME, only to get dragged here there and the other like a show pony.
