Omfg I swiped right on my brothers bff

I hopped on Tinder as I haven’t been on it in awhile Iol I login and I’m face to face with a familiar face I was like wait....I know this guy Than I was like ohhhh my god it’s my brothers best friend who I haven’t seen in 10 years. I debated for 20 minutes to swipe left or right... NO WAY he’d swipe right he hated me than. I said screw it and swiped right to pique my curiosity and omg he also swiped right and I don’t think recognizes me at all....

He still hangs with my brother...

I’ve know this guy since I was 12 lost touch with him when I was 23..

Now I’m 33 Iol

Do I message something friendly like Hey Chris?
