Having chats with #Snapchat about #friendshipgoals with my #BFF Bestie @lisasurihani and how we have come out stronger as friends over 20 years of friendship. My biggest takeaway from today is finding out how 52% of us value social media interactions as appose to 57% who value personal interaction between friends, that Gen Z value smaller groups of friends and are more private about what they share and that I LOVE @lisasurihani so much! my realtionship with her stems from being kind, honest and silly with one another. Thank you #Snapchat for allowing us to come and share our friendship with all of you! ❤❤❤ #frompamperstogrannypanties
