Good for them! Although a better gift would be bitcoins + a bouquet simply for the sentiments.  I mean just imagine telling your girl "I got you bitcoins" no problem if your girl doesn't mind but where's the romance in that, it would be smoother to give them the usual flowers/chocolate and then just mention that you also gave them a couple of bitcoins.

I just wish it was the same where I'm from though, based on the data a lot of Russians are already open to the concept of cryptocurrencies.
