Pavlov's Forty-Ninth Law states that every glass you break will be the first of a set. The house will thus be full of sets of glasses numbering three, five or seven.
There are, however, two silver linings here.
Silver lining #1: it further encourages one (as though any further encouragement were needed) not to hold dinner parties of the Noah's Ark variety, the kind to which people with no official/acknowledged/visible partner (of the opposite sex; this convention must drive gay and lesbian couples straight up the wall) never get invited unless the hosts accidentally find themselves with a 'spare' guest. In such cases, one is usually invited on the afternoon or even early evening of the dinner in question.
One should accept such invitations only if one knows the food is going to be good. While Noah's Ark dinner parties are usually dramas with double or triple parallel subplots -- extra points if any of the subplots are, so to speak, intra-couple -- to rival Shakespeare's, the dialogue is usually substandard.
Silver lining #2: The kitchen floor gets swept. Properly.
