Feeling left out

I often feel as if I am not fully participating in average teenage girl activities. This sounds selfish and ridiculous is comparison to real world problems. Anyway, in my small teenage girl mind its traumatizing.

1. When all the girls get ready for a formal evening. Them, "OMGOSH! I am going to do my hair like this!" or "Omgosh, my hair is so staticky" or "Omgosh, my hair takes so long to straighten/ curl"
Me: "Well, I am just going to put my hair up in a bun with a nicer headband, hopefully my bald spots won't show as much."

2. When they want to do a photo shoot.
Them, "Omgosh, this angle, this angle!"
Me, "Nope, just gonna stick with this angle, maybe my hair won't look so thin." or "Darn, I have to remember another time where I have thin hair while all my friends have gorgeous, perfect hair."

3. Pool Party
Them, "Hahaha! Don't splash me! Oh, my hair is wet! Now it will be freezy!"
Me, "I get ear infections when I swim, I am just gonna sit this one out." As you sit on the side looking at how much fun they are having.

4. At the cottage/ beach
I try to avoid all situations in which I have to get wet. It doesn't work when people are splashing and jumping in around you. You kinda look like somebody who rather  be somewhere else.

Any moments in life you feel you don't fully get to participate in....?????
