There’s so much chatter (be it written or verbal) about how people aren't actually talking to each other any more. Everyone, even in the same proximity to each other (at a bar, at a restaurant table, etc.) seems to be on their phones. We also aren’t actually talking on our phones anymore. Phones are primarily used for texting, email, taking photos, and social media.

Here’s a suggestion: SHOW UP.
I haven’t had a wedding. I haven’t had any babies. But I have shown up for most of the showers, bachelorette parties, weddings, baby showers, “sprinkles” (have to admit – that one is lost on me), and milestone birthday parties (or weekends away) I've been invited to. Do I do that because I feel obligated? Do I always have nothing else to do on those days? No, I do it because I value the human interaction and celebrating milestones & achievements with those who are important to me. And I understand it is important to them.
I suppose there’s a pecking-order for what people consider significant life events. My milestone birthdays are important to me. My master’s graduation party was important to me. I don’t think people didn't “show up” because they didn't want to be there or that it had anything to do with me personally. They prioritized something else over my celebration and I get that happens from time-to-time.

Here’s a suggestion: If you don’t show up, make an effort to let the host(s) know.
And, finally, take a minute to think about the occasion and whether you really need to skip an event because of the reason you have before you… and know that simply showing up can really mean THE WORLD.
