There is a right and a wrong way to eat pasta - and it usually entails a fork and sometimes a spoon.
1. Purists (and many Italians) reject the spoon! Take a small amount of pasta near the edge of the bowl and twirl until you create a little nest which you then pop oh-so-elegantly into your mouth.

2. It's equally acceptable in most establishments to tackle the strands with a fork and spoon. Similar principles - take a small amount on the fork and, using the spoon as a base, twirl to make a neat nest and straight into your mouth.
Either of these two will see you maintain your decorum in the face of spaghetti or fettucine or buccatini with aplomb. Just remember that you want a tidy nest on the fork, not a slithering, dripping mass.
3. Originally, pasta was eaten with just the hands - straight to the mouth. While this is a 'traditional' method, we don't recommend it if you want to dine with your friends again.
