I never have alcohol in the house, other than an occasional bottle of wine that we get as gifts and give away as soon as we find someone who wants it. LOL
We don't drink wine, Dh doesn't love beer, I hate it, so there's never a need.
Ii am not a teetotaler and do drink at weddings and DH's Christmas Party and fire dept dinner..and very occasionally I'll have a margarita at the Mexican restaurant we go to--probably 3-4 evenings a year I drink.
That said, I have no problem with alcohol being around, though I would NEVER get drunk if I had my children with me.
We never serve alcohol at the backyard parties we throw, but it is BYOB if you choose to, and if people choose to bring it, that's absolutely fine.
I was surprised, at DD's end of the year T Ball pizza party, they had little nips of MGD..not disapproving but a little taken aback.
My husband did have one and it wasn't an issue. No one got drunk though, and if any parent got drunk at their child's TBall party I would 100% be thinking how trashy they were.
ETA: No wine or beer has ever been served(or brought) at any of my childrens birthday aprties.
They are only family parties and both my family and my inlaws are the same way-why have a beer when you can have a soda, no one on either side is the type to have a beer after work at home, so any beer we bought would most likely be unused after the party was over. A waste for oour families.
