The street is not just a venue for chaos and darkness, but is also a setting for positive feelings to flow.
LOVE is visibly seen.
Unmindful of heat and burden, Daddy selflessly carrying little boy to see the parade.

Comfort in the arms of significant other
But avoid too much PDA.
Disclaimer: I am no paparazzi, but I just find it uplifting to see expressions of love in the streets.
