My sister is one of the people you mention that post a ton a photos from vacation and fine dining experiences. I think it definitely can be excessive and some of her friends admit they are tired of always seeing her updates and photos since her life looks so "perfect".

But I think the key here is to just remember that we are all human. While Facebook is a quick platform of sharing your life with friends, I hardly ever see people sharing bad news or sad ones. It's usually an unbalanced image of all the happy and fun times. Again nothing wrong with sharing happy moments. The problem becomes when its TOO much of the filtered photos and news which is also filtered to sculpt a persons life into looking like it is perfect. In reality, life is not perfect. Social media is all a construction...kind of like makeup or photoshop.

So if you remember this tidbit, you don't need to worry about the feelings that naturally come up such as jealousy or annoyance that your friend can post 100 photos from extravagant vacation getaways. If it really bothers you, turn off their specific notifications. But remember that this person is still just a person in real life. There is no one who simply "has it all going for them". If there were, we wouldn't be so obsessed over our social media images the way we are.
