i am not a fan, i don't like it. as you said it, it does only ruin the day if you for example you did planned a date or a meeting with a friend. rain also causes traffic and what if you finished work and start raining? the journey to come back to your house will be 1+ hour than it usually takes, dinner will be already cold or in the worst case you still need to cook, do you imagine how long your day is going to be cause of rain? the only time i think i can stand it its when there are continuous sunny hot days without a break, in that case i would forgive the rain and leave the nature do its work
