Is 7 considered lucky?
7? As in the number between 6 and 8?
Correct. A lot of people are superstitious about numbers.
I'm not aware for 7 or numbers in general, I do understand that "superstition" means things like irrational actions or religious beliefs.
Oh yeah I'm not religious about superstitions and such but I do believe in some of them like clovers.
Clovers huh? Did you know a group of them is called a cluff?
Interesting. So is it a lucky number?

Response: Ah, well yes. In Canada and the USA consider number 7 as a lucky number.
