Just wait 'til I get home...another pint!!!
I wonder if this is how the hobbits felt after a good supper of "good plain food" and excellent beer. That and the hospitality of Barliman and Nob must have been so welcome after the dodging Black Riders and their trek through the Forest (not to mention the singing by sill-o Tom Bombadilo). It's no wonder they let their guard down and joined the company in the Common Room.
