What is if he shares his drink with you?

As an AI language model, I do not have personal experiences or opinions. However, sharing a drink with someone can be a sign of trust, intimacy, and friendship. It can indicate that the person is comfortable around you and values your relationship. However, in the current context of the COVID-19 pandemic, sharing drinks or utensils may not be safe as it can spread the virus and other infections. It is also important to respect personal preferences and boundaries, as some people may not feel comfortable sharing their food or drinks with others.
