Definitely bird crap .... I've already had that happen to me once. I remember someone told me at the time it was good luck. I'm pretty sure that was to make me feel better about being crapped on by a bird though.
Step in dog poop. I have long curly hair, so trying to wash bird poop out of it would be a nightmare! The dog poop would be easier to wash off I think. I've been pooped on by a pigeon before anyway (all down my arm!). It wasn't fun, especially as it was right before my A Level coursework deadline which I was on my way to hand in!
I had just completed a 16 km race in western Sydney, took off my Nikes which were so new I'd hardly worn them in and stepped on a dog turd. I was so pleased I didn't get it all over my new shoes.
I'd much rather step in dog poop. Bird poop can be toxic. I had an uncle that went blind in one eye from a bird bomb.
I pick up enough of Hunter's crap in my yard that I've stepped in it barefoot several times. Once this morning when I took my shoes off to swim and cool off. Hose just warshes it off until I can shower. No big deal. Anyone who has had a dog knows the feeling ! LOL
neither.
Bird. Yeah it's disgusting, but I can wash my hair, and bird crap is not as offensive as dog crap is. I've stepped in dog poop before and the smell was really hard to get rid of. Ended up throwing those shoes away.
