Translation:I hate going to the car boot sale.
We don't have garage sales in the UK - i.e. people selling loads of things from their own home. A Car boot sale is an organised event where people pay to park their car and sell items from it (so there can be hundreds of cars at the event), then people come along and buy from them. It's like a big (sometimes very big) market, but the traders can be both professional traders or individuals.
I've never bothered typing any accents on letters as it's much quicker to just type the normal keyboard characters - just remember that they are there. I think I've only come across one case where it's vital to get the accent correct.
If you really want to bother typing the accents, use the keyboard and the Unicode symbols (look them up from Character Map), or try "To bach", if the symbol you want isn't showing in the options.
bear in mind that a "trunk" in the UK can be either the big, fat, vertical part of a tree, or a big chest for travellers, or the long nose on the face of an elephant :-) (Likewise, a "boot" is one of the big shoes that we wear on our feet in Winter, as well as the luggage compartment at the rear of a car). Don't you just love the differences in the English language in different parts of the world? :-)
