Oh, thank you I'm sure he'll appreciate that

The party is tonight, so we're kind of busy preparing it right now. I made him a giant chocolate cake

You have to be 18 to drink in bars I guess? It's the same here. But I don't think you have to be more than 16 to buy beer and stuff in the supermarkets. I don't really remember

Have a very nice weekend, I really hope you'll have fun at your friend's birthday
