HELP! NEED ADVICE EASY 10 POINTS FOR BEST ANSWER?!?

Okay well my so called best friend (Bre) and me and this girl who always changes her best friend (Sammy) and this other girl (Jane) and another (elizibeth) Were all waling to a restaurant for lunch. We get one hour for lunch and it is a 20 minute walk to the restaurant. Me and Jane are those kind of people who do not like being late so we ran and left the rest of them behind us. So any way Elizibeth doesn't care yet Bre and Sammy care.They didn't seem angry but they were.Sammy who has a habit of changing her best friend and stealing other people best friends decided that her and my best friend bre would never talk to me again. okay i know they will talk to me in a week or so but bre is going to become her bff. The wouldn't talk to me the whole lunch i would go up and talk to them and they would turn there backs and laugh bre my best friend apologized i said okay i forgive you but your going to do it again. And me and Jane knew if we staid behind with them we would of been ignored! So what was the point in walking with them. Well my 2nd bff is gone on vacation and jane is not really one of my really good friends im super upset about this whole thing and afriad of loosing my bestie! Any help/Advice
