Marriage and Whatnot

Something that is crazy weird for me right now as a YPK (youth pastor's kid) is the people I grew up with are all getting married and having children of their own. It's hard to explain how I feel about this because it's honestly one of the strangest feelings that I have ever experienced. I feel like (even though I'm only 18) I should be right along there with them because I grew up with them. It seems that I should be 24 or 26 too, but I'm still in high school and have 5 more years before I'm to the age they are. It's so weird. I wish I could fully explain it but if you're a YPK and roughly my age, you'll understand what I mean. When I was younger I didn't understand the whole age gap thing, I just felt like I was a teenager too. I'm actually starting to notice this same concept with my younger sister as well. She will be turning 3 later this month but she tells me that she's a teenager too! haha like I've clearly expressed.. so weird.
Below is a picture of me when I was younger (probably about 6 or 7).
