How to lie during the holidays

Ha

My mom always makes a special sangria for every holiday and while I’m not a big drinker to begin with, I’m worried someone is going to ask why I’m the only one not drinking it. I will be the only one because it’s a small group of people and usually we all drink it. What lies are you all telling to avoid suspicion? Or are you just going to say you don’t feel like drinking it and hope that works? 🤔 We plan on telling all our family members in December but today is Thanksgiving in the states so I need to be prepared with an excuse haha
