Open to a group of girls

[kingofthetrees]

hey guys mike again i know canned openers are stupid in highschool but say you see two girls walking together in the halls. what can i say to get there attention and start talking to them(the rest is easy im good at convo but not openeing) approach anxiety is no problem either. that being said how can i open a set of 2 to 3 girls who are walking together?
Note: like some examples of what to say

Say hi, ask a question, then walk away. Next day say hi and talk normally. It's no different than a 1 set in high school.

Remember, you're most powerful openers are hi, hello, and hey.
