Keith: at the grocery store. You both were in the bread section. The store was busy, considering it was Saturday. You bumped carts, and exchanged a few words. Later, you ended up behind each other in the line.

Lance: you went to his high school. Later, you went to a community college for two years, and then switched to his university. You share the same minor.

Shiro: you both were planning on sitting under the same tree in the park.

Pidge: You were selling a video game on eBay and she was interested in buying. She noticed you were also selling other items she wouldn't mind blowing her money on, and you two began conversing.

Hunk: you were buying from his small lemonade stand that was mainly for the kids running around the neighborhood, but you had come by it while yardsailing (yardsale-ing).

Allura: you were in a floral shop, looking for flowers for your mother. She had entered, and you two conversed. She just wanted more plans for her home.

Romelle: Your best friend/mom dragged you to a boring old person game night. Romelle was there, and having a blast.

Lol yes this was also from an old book of mine. Thinking on republishing a few.
