What are the subtle, telltale signs your Q has been drinking- even if they try to hide it?

My theory is that all of us have developed an extra sense to detect when our Q has been drinking. There are small giveaways.

After a year of marriage, I can easily tell when my husband has been drinking, even if he manages to hide it well. The most obvious signs are that he becomes really snappy and almost confrontational. He has these go-to phrases like, “this is not nice” or “you hurt me, it hurts,” no matter what I say. He also starts using his hands a lot while talking, and his voice goes up a pitch. Without fail, these signs give him away every time. He knows I look at him with disappointment and without me questioning says “I haven't been drinking, is this the Spanish Inquisition??”
