I love it when he shares whatever I am drinking. I always offer to get him whatever he wants. Sometimes he won't say no to his Guinness, and its not likely for me to be drinking beer. Unless its Sam Adams in October, but thats a whole different love story. Anyway, if he isn't in a beer mood, often he will just sip on my glass of wine or whatever I have. Its funny that such a little "thing" would seem so intimate. To one person, it might seem like nothing, but to me it is very warm and personal. It is a comfort to pass the glass back and forth. Maybe its just a reassurance that " I like what you like". Share my drink, share my life, share my love.
