Next time if you want to join ask to tag along. Extroverts don't recognize the need to reach out. Don't get down focus on what's going ok. I'm an introvert I know how painful this can be! Take care
I read your post about being introverted.
My father told me; " there are two type of people in this world. Takers and givers. Stay away from the takers "
Hope this advice helps a little bit.
I will give everyone a chance but I'm very careful about who I actually become friends with.
I look at Facebook & can not understand how so many people have 200 friends.
