First of all, you shouldnt give anybody a "nice bottle of whiskey" as a gift. Whiskey is hard liquor, and for all you know, he could be a struggling alcoholic, and this could cause him to relapse. How will you feel if he drinks it, then drives drunk and crashes his car into a tree and dies? Or he could even run over some little kids in a crosswalk. Alcohol is never a good gift, unless it's a mere bottle of wine if you are attending a dinner party. No. Do not give this gift to your boyfriend to deliver to his dad on his birthday. And don't you wait until your day off from work to give it to him yourself. Get him a tie, or a box of handkerchiefs instead. It doesn't matter who delivers this gift to him, and it's okay if it's late for his birthday. He will hate it, but at least it's a safer gift than whisky. That was a bad idea on your part, and just shows how thoughtless you are.
