Random thought spurred from Random invite

I have a baby shower to attend tomorrow. I knew the girl from High School but we haven't really bonded much since then. I'm just wondering if anyone think it's peculiar for someone to invite random people to showers or weddings for that matter. This brings me to one of my best friends in Junior High, yup I said it Junior flucking High. She married her long term boyfriend and invited me to the wedding. Perhaps it's my sometimes anti-social ass who finds this strange. But if I don't par with you and haven't spoken to you in say damn near 10 years chances are I'm not inviting you to shyte. Tell me what do you think...
