Hi everyone. My sisters and I adore our dad. He has a heart of gold, and is always there for us. He is a grandad in a million. Like everyone, he has his flaws, and his is drinking too much. Think functioning alcoholic, rather than sometimes overindulging in his favourite drink. His attitude over the years has been 'all or nothing', so either he's on medication for it or on a bender.
He has a very responsible job, and is otherwise fit and healthy (believe it or not). He walks absolutely everywhere, eats well, and the world would need to be at an end before he missed a day of his work.
This morning I received a message from my sister, to say that she had just spoken to my dad, and he sounded pissed. This being at 9am. We've had years of this, and she's the closest to him, so can tell a mile off.
This is a very worrying development, as we have never known him to be drunk at this time. Usually he would just stop at night. So she sent us siblings a message, asking what we should do. I said that I would phone him. Sister straightaway came back with 'don't make it obvious, as he'll realise we've been talking about him, and that would be grim'.
Alcoholism really does run in my dad's family. And it has always been swept under the carpet. I'm not really into this, and prefer to try and deal with the situation helpfully and sensitively, but head-on.
So I phoned dad and here's how it went:
Me - morning dad. How are you today?
Dad - (mumbling and very obviously pissed) I've got a bit of a cough, and I'm not feeling good.
Me - dad, are you sure that's all that's wrong? I'm worried about you.
Dad - what do you mean you're worried? There's nothing to worry about.
Me - dad, have you been drinking?
Dad - me, drinking? Are you mad?? I told you, I've just got a cough.
Me - dad, you sound drunk, and I'm worried about you. We all love you and care for you, and don't want anything to happen to you.
Him - more denials, mock outrage, etc.
My sister is now really fucked off with me. She said it wasn't the right time to confront him, and she's probably right 
Do you know what though, if your dad is pissed at 9am then that's a whole new low, and does it actually matter if he thinks we're talking about him or not?! We're beyond that now, surely.
The other point is that nobody is holding a gun to dad's head, telling him to answer his phone at these times. He chooses to pick up and then gaslight us. So it's him treating us like the idiots, rather than the other way round.
I've fucked up, haven't I? I should have listened to my sister, who suggested getting a family member (one of his siblings) to discretely check in on him. I live a few hours away.
Please be kind. And don't say 'he's not a good dad, because if he was ....' I don't want to hear that, because you don't know him or his history. And we think he rocks, in spite of his flaws 
Thanks.
