Many persons who eat pasta do so elegantly.
Some do not.
It really depends on the use of the fork. If you twirl a few strands of pasta on your fork, it will be not messy. If you just take a vast amount of pasta and suck it in, that's more messy.
Don't be messy.
1) Take fork
2) On the edge of the plate twirl until pasta forms a ball on the fork
3) Eat.
4) A spoon is a better option.
