Girls, Should I tell my friend to wipe her vag after peeing?

I can't believe I'm even asking this... I've seen my friend pee recently, like at my place and hers just when we've been talking in the bathroom, and both times I noticed she didn't wipe. There was toilet paper there so no real excuse. She just kind of finishes her pee, gives herself a quick shake and pulls her underwear back up. Should I say something? It's quite embarrasing to even think about it.
