Cheek kissing

Cheek kissing is when people touch their cheeks together to show affection or say hello. Like when you give your mommy or daddy a kiss on the cheek to show them that you love them. People in different cultures may use cheek kissing to greet each other, but it is important to remember that not all cultures do this. Sometimes people kiss cheeks twice, once on each side, and sometimes they only kiss once on one cheek. It's a friendly way to show someone you care about them without having to give them a big hug or shake hands.
