Allright then, I guess I would drive around, see how fast it goes and what other stuff you can do with it. Probably not take it apart, if I would get it apart at all I wouldn't know what everything is. Also I wouldn't be able to put it together again, making most parts useless.
How do you write your capital Ls?
I assume you mean opening of a letter (googled it)? I don't write a lot of letters so don't have a standard opening. It really changes from letter to letter (usually there is like a half year in between, and nearly every year another Dutch or English teacher at school teaches you another opening lol). Most commonly they tell us to use 'Dear Sir/Madam,', but googling that it seems 'Dear Sirs' is more common in the UK which we are supposed to learn at school... Always found it confusing stuff, those formal letters. One year 'this' is absolutely the right way (teacher: "You probably remember it wrong, I can't imagine they taught it you another way"), and the next year it's another.
Informal, I never wrote an informal letter outside school. Short emails or IM conversations just start with hey or hello (sometimes with the name of the person I'm talking to and/or a smiley), or a Dutch translation of that.
