[update] Proverb, by José

One swallow doesn't make a summer ( uma andorinha só não faz verão)

I've chosen this proverb 'cause I  think it is true. When it says that it's very hard for a person to do something without anyone's  help  it's because one need to join a group to do a certain  action . Another reason for me choose it, is because I listen to it all the time in my neigborhood.
