Lol. My brother's Lego collection absolutely played a role in my sister-in-law dating him for the first time.

I caught the look on her face when a group event happened to pass his meticulous thematic curated collection. His roommate was hosting an event while my brother was out of town, I think.

She "casually" inquired who built all that, but I swear I saw a "he could get this" look on her face.

I kept my mouth shut about what I saw, but they are married, now, anyway. Lol.

There's more to it, he's a fantastic guy. But yeah...first clue for her was his Lego collection on display while he was out of town.
