You go whenever you want most people go at night just when the party gets started but if you want to be there early since the start for your friend i advice to go early even to the church (if she having it) and you meet your friend however a hug shes your friend and her parents i advice a hand shake but if they seem nice i say go in for a hug and a kiss on the cheek (Its not weird at all alot os mexicans so that)
