The last time we saw Albert, he showed us a quick mnemonic to remember which drinking glass (and which bread plate) is yours. Inevitably at some event such as a wedding, someone starts things off by grabbing the wrong glass and everyone at the table is subject to that first bad decision. Hopefully, this will help avoid those situations.
With your left hand, you make the letter "b", which tells you that the bread plate on your left is yours. With your right hand, you make the letter "d", which says that your drink is on your right. Simple, huh?
