spanish costumes (constumes like a disfraz or contests?)

Today it is sunny,; it is spring. I like spring because everybody is out in the street. Here in Spain, there is a costume, when spring arrives, where lots of bars cook snails and there is a competition to decvide which it is the best place cooking them. I like to eat snails,; they are delicious with a [freeze bear cervesa?] [frozen/cold beer] and in a good company. My sister is a good cooker and she usually prepares a big pot of snails due to her birthday. and My family and I we spend this the day in the country. Ourr children enjoy a lot of running and playing there. If someday you visit Andalucia in the spring you should taste snails.

I hope my comments were helpful.

Homework (This entire paragraph seems to be written in a very reflective manner.  It is as if you are inside your own head.  You seem to be telling this to yourself.  I hope I accurately understood you.  I have suggested changes based on my understanding of your intentions.)

In this moment iI'm doing much a lot of homework,; I have 3 days trying to finish it but I can't.
I have static's homework with thrity six problems about the forces and moments. I'm so tired and stressed, that's why now I'm writting on italki to relax a moment.

No worries Seergio. I often feel the same way.  It is nice to take a break from our work every once in a while.  I can assure you that my Español is worse than your English. Keep working hard.  I am sure you can achieve your dreams!

Mike I was about to say that I could tell you are very creative and then you mentioned that you were a designer.  How cool!  With your permission I will just make a few adjustments below.  I hope they help you along.  I enjoyed reading your entry. If you have any questions in general or about my comments feel free to ask.  Good luck with your studies!

Why I learn English.

Today l listened [to] music, read [the] news, watched TV and so on...But it was English music, English news, English movies. English [is all] around my life. Every side [of] my life is connected with English. I am [a] designer and most new information about my profession [is] written in English.
And once I said: "If I learn English i will be another person. I will be better - more smarter, more beautiful (inside) and etc."
If you study some language - you will be better. I believe in it. Never give up. You can speak English.
It's time for the next idiom. Today it is "Ничего страшного". Maybe it isn't idiom but Russian people use this phrase very often. Translate word to word 'Nothing terrible" is not correct in English. In English it may mean "Okey", "Don't worry", "Never mind" and other. For example:
- What is number our class?
- Six, but it still busy.
НИЧЕГО СТРАШНОГО, I'll wait.

I did not fully comprehend your example, but I think I understand the meaning behind the phrase or "idiom" as you described.  It seems "Ничего страшного" means "It's OK."  Yes?
