Well just take a sip while they don't see, it's not about getting drunk it's about the taste. Also if it's wine first you smell it and drink it after do get a fuller taste.
you are not talking at me right? XD i know right? XD XD the smell of the wine is even better than the taste, sometimes i just smell it for 10 minutes and then i let my parents drink it... smell is the best part.. don't forget to let him take oxigen
