I need some advice.

My sister invited me to go to SM with some of her friends. At first, gusto ko since I wanted to buy some things in SM... kaso nga lang, hindi ko kaclose sila and I am pretty sure na iignore lang nila ako. I thought that maybe I can just make friends with them but it will be hard since they are older and practically thinks of me as a baby. What should I do?

a. wag sumama sa kanila.

b. sumama ako pero I-ignore ko lang sila.

c. sumama ako pero try to be friends with them.​
