Why do you a lot of us get embarrassed with our parents -- more so at young ages like our teenage years -- if we run into someone we know at a store or something, even if the parent is there, but not with you? For me personally, I used to be fine if it was an adult friend (e.g., the mother of one of my friends) that my mom was also friends with, but if it was someone I knew from school, for example, then I just felt all weird inside when I talked to them. Now I'm better, but what causes us to be like this? Most of the time our parents don't even do anything that would make us embarrassed, but we feel embarrassed, anyway.
i think it's just a phase we go through. i think it's just a time in our lives in which we think we would be judged by "hanging out" with our parents.
I only felt this once and it was more to do with me not seeing my friend in years and having nothing to talk about while my mom talked with my friend's mom like they were best friends who see each other all the time, even though they were really only acquaintances. So me and my friend (we used to be best friends before I changed schools) stood awkwardly while our moms chatted away. I've never felt embarrassed about being seen with my mom though. I don't know why, I just never have.
I don't often get embarrassed by my parents. If I run into any friends while i'm out, and my parents happen to be there, nothing changes for me. Most of my friends I talk to on skype anyway, so most have heard how odd my parents are anyway, why hide it? Although, if I had to take a guess at why others got embarrassed, I would say it's because these days there's a lot of pressure on people to be "cool" or at least look like they "fit in" and a lot of people are convinced that their parents could ruin that image.
