dependence on parents - my opinion

before i start, i am not meaning to be rude to people who hang out with their parents and/or have a good relationship with them, i am just stating my opinion on the matter and what i have noticed. i realized i have been using blogs wrong, so i want this to be my first real blog with my opinion. i am very happy and glad if you have a good relationship with your parents.

firstly, my relationship with my parents are good. i am the oldest sibling in my family. i hang out with my mom sometimes in my free time and we have a very good relationship, i tell her about all of my problems. i don't hang out much with my dad, but we get along and i am able to have conversations with him. my parents are chill and let me do a lot of things, like hanging out with friends and throwing small gatherings with my friends. i do have to let them know where i am and where to pick me up, but other than that, they are cool with me doing whatever as long as i tell them and i don't do anything that can hurt me. 

recently, i have started to notice a couple of my friends dependence and relationship with their parent. one of my friends, who is a only child, is always hanging out with both her parents, all of the time. when she comes over to my house, she is constantly texting and calling her parents the whole time. i have met her parents, and they aren't strict with her, she has never said anything about them forcing her to text them, because she will text them about basically everything we talk about as we talk about it, like drama and stuff like that. it feels weird to me, because we are 16-17, so i don't understand why she feels the need to tell her parents everything in the moment it is happening. also, when i go over to her house, we do everything with her parents and sometimes, she runs off with her parents and leaves me behind. i completely understand that different people have different experiences and home life, but i am worried about her future because of her heavy dependence on her parents, because sometimes, she doesn't even remember small things about herself, like her middle name or where she went during the weekend, so she has to ask her parents and it concerns me, but also confuses me because she has no interest in independence and it scares me for her future.

another thing, i hung out with a bunch of my friends the other day, and my friend that invited me out had her mom stay with us the whole time. her mom was very nice, but the whole time, i felt uncomfortable expressing myself in front of her because i have never met her mom before and i am not good with acting chill around my friends parents because i want to look like a good in front of them. it just felt weird because i wanted to joke around and have fun with my friends, but it felt weird when her mom was there the whole time. i just don't understand because we are around 17 years old and i feel like people should be a little more independent from their parents at this age when hanging out with friends. 

i again, am very grateful my friends have loving and amazing parents who they feel comfortable hanging around with and who love them, but i am just confused by how they want their parents so close when hanging out with friends and how some of them dependent heavily on their parents. what are your guys thoughts?
