Secret booze
During family gatherings, there can be a lot of kids running around so alcohol needs to sometimes be kept away so none of them accidentally drink any of it. Some adults just do not drink at all while they are with their family and others need a drink desperately, so they have to find alternative ways.
If you are ever in a situation where you are with extended family and need to drink but can not do it in front of the kids, just hide the alcohol in a stocking. The kids will never be able to reach it and no one else will ever think of looking there for a drink.
