Maybe your girl want to go to a holiday in Italy and stay at the nice hotel like the hotel anglo americano roma and you want to save the money in a online saving account.
This kind of questions is very normal for a guy that just got a girlfriend because the girl like to spend money on fancy trip and nice hotels like the hotel anglo americano roma. You on the other hand normally want to put the money in a online savings account.
So the best solution for you is to tell the girl that by saving the money online you can afford to take her hotel anglo americano roma later this year. That way you make her happy and you do not loose money and in a few years your 10 dollar will become enough to travel to the hotel anglo americano roma.
