Is it normal to kiss on the lips as a greeting?
Depends.It depends
Yes, kissing on the lips can be a normal greeting in some families, friendships, and cultures, though it isn’t everyone’s thing. The key is that both people are comfortable with it.
Greeting kisses vary a lot by family, culture, and social circle. Some people grow up giving a quick kiss on the lips to relatives or close friends; others stick to hugs, cheek kisses, or a wave. Neither preference is strange.
Pay attention to the other person’s cues, and don’t assume they’re up for it just because you are. If you’re unsure, a quick “Are you a kiss hello person?” keeps the greeting friendly without making anyone dodge at the last second.
