Be a little spontaneous.
“OK super last minute and random, but I’m actually going to be in your neighborhood if you wanna hang out or get a drink or something. No pressure tho”
Find something in common and related activity you could do together.
“I’ve been a basketball fan since birth lol. Want to go to a game sometime?”
“I’m obsessed with horror movies but all my friends hate them! Please come with me to that new one that just came out, seriously i’m desperate haha”
If you don’t have anything in common, ask them to show you something they’re good at.
“I’ve never been sailing in my life and might capsize the boat, but if you’re willing to take the risk we could go together sometime!”
“I’m the worst ice skater on the planet. Wanna go to the rink and give me pointers, or just laugh at me when I fall? haha”
“Dang I’ve never tried rock climbing before, would you teach me??”
Issue a playful challenge.
“There’s no way pizza is the best food in the world. Let me show you my favorite sushi place and completely change your life”
“You’re definitely not a better bowler than me. We need to settle this. You, me, the bowling alley, Friday at 6”
