Ladies, would you wave goodbye to a male friend?

I went to her house to get a ride from her brother, which turned out to be a miscommunication. When I was leaving she waved goodbye. Does it mean anything?

I may be over thinking this, but it just seems odd to me. I can't really remember waving goodbye to anyone.

Yeah, I figured as much. It just got me wondering and to me it just seems so...pointless I guess. It's weird. swinging a hand in the air to say goodbye. maybe that's just me.
