Kissing adult children on the lips

I’m curious to know, do you kiss your parents on the lips? I’m a grown woman in my 30s and every time I say bye to my parents we always hug and kiss on the lips. My husband thinks it’s weird but I grew up always seeing this and I think it might be a cultural thing (I’m Italian). Is this weird to you?

Wow I didn’t realize my family was odd for doing this. Just to clarify it’s a peck, not a sloppy drawn out smooch lol. I also kiss my grandparents like this and my kids who are 10 and 12. It’s never occurred to me that’s it’s strange. Thanks for the input, I’ll have to tell my husband he was right hah.
