a) may 5th is a mexican national holiday. mexico is in central america, not south america. there is no reason for people in any south american country (argentina? bolivia? venezuela?) to celebrate a mexican national holiday. in the united states, we don’t celebrate australian national holidays.
b) a spanish newspaper? in south america? they had imported newspapers all the way from spain? must have been expensive.
c) in mexico, they do celebrate cinco de mayo. it’s a mexican national holiday.
No they don’t. They don’t care much about it. They care about one in September.
