In medieval period they used to deliever letters, secret messages and they really earned a huge respect in our hearts...
Then they got competition from horses...postal services etc..and finally their hardwork and services of centuries are forgotten by us.
They realised how mean and selfish humans are ... and as a revenge they are pooping on our cars, rooftops,literally everywhere...
I want to meet the guy who used pigeon in the symbol of PEACE...
