Sadly some people are just assholes like that. I always move pretty far away from people that are on the side of the road while it’s raining and puddles out. It’s common courtesy but some people are lacking that and actually get a devilish sneer out of doing something as evil as that.
Hopefully you had a better day the following day! We should wake up each day and start anew, so that we don’t carry the negativity from the previous day and allow positivity to flow in us as much as we can.
