What to buy a friend who is moving house from UK to France ? There are many things to choose from that will send them off to their new life thinking of you.
If they do not speak very good French, there is always the option of a dictionary or language course on CD. Another practical idea is a book on either the region they are moving to or one specifically designed on living in France, and there is an excellent selection of these available.
Invariably there is always some part of England that they will miss, so a fun gift may be to remind them of home with a carefully selected hamper of English food that is unavailable in France. If they are feeling homesick, then a cup of Horlicks will do the trick and don't forget the imperative gravy granules!
You could also consider sending them a plant or floral arrangement to be delivered after they arrive. This way, they will know that you are still thinking about them.
If your budget is tight, then there is still a very special present that you can give them. Spend time to research their new local area on the internet, and print any relevant or interesting items - any attractions in the area, social groups to join based on their hobbies, local bars and restaurants. Then collate these in a folder and give this information pack to your friend.
This combined farewell and good luck gift will remind them of you, as well as helping them in their new life.
