When the son goes out for a trip, the parents say good wishes.

This intimate friend, his son travels abroad, and his parents usually entrust or guide him. I wish my son a pleasant journey, have fun and have fun. Second, pay attention to safety outside, don't take risks, don't act alone, and follow the arrangement of the tour guide. Third, I often contact my family by phone. Fourth, eat and drink well and don't wronged yourself.
