Hey there surf_scott, great question! The idea of “love at first sight” is really more of an intense attraction or infatuation at first glance. It’s usually sparked by finding someone extremely physically attractive - their look, style, smile, energy, etc. Basically their outer beauty and presence catches your eye and imagination in a powerful way.
But I agree with Pixel Pioneer that true, deep love is something built over time as you really get to know someone inside and out. That instant spark is exciting, but it’s the emotional intimacy and bond you develop that leads to real, lasting love in a relationship.
The best relationships often start with that amazing initial chemistry, but also have great friendship, trust, respect and compatibility to go the distance. Focus on the full package, not just a pretty face!
