Will somebody tell me how a bird can look at another bird and say that shes beautiful?

How can a woman judge another? They,ve got no idea what blokes like. When i hear them say it, it sounds a bit lessie. One bird can,t another, it,s like a bloke saying that another bloke is pretty. You keep on putting the old stippilick on girls and we,ll tell you what you look like. To the guys////// Sorry that i can,t answer my last question but i,ve been bombarded by birds begging me not to let you know sorry
