You can say " Voy a estar con mi mejor amigo/amiga mañana". (male/female)
The zoo
I'm not going to Hawaii, but if you and your friend are then you would say: "My best friend and I are going to Hawaii"
In spanish, "best friend" is mejor amigo(a), amigo is for a boy and amiga is for a girl.
If you were to visit Mexico tomorrow, the best way that you would know that it was once controlled by the Spanish is the prevalence of the Spanish language.
I believe its.. "You and my best friend are going to Hawai'i this summer."
The correct sentence is: Me and my best friend are going on a exctotic trip to hawaii
mejor amigo (or amiga if the best friend is a girl)
Por mi amigo mejor. - By my best friend.
What is your best friend like? (the best friend is female)
Maintain both. Tomorrow this "tragedy" will be forgotten.
Best of luck to you my friend is very easy to translate. Best of luck to you my friend = mejor de las suertes a mi amigo
tell him he is going to have to deal with it because she is your best friend and she will always be there for you and you dont know how long he is going to be there for you i would rather loose a boy then my best friend
