Hopefully it was a little bird!
I'm not superstitious, so I wouldn't say it's a sign. You were in the wrong place obviously. Birds just let it go wherever.
I've had it happen once. Certainly most inconvenient!
With buildings if I'm walking near them, I check the walkway area...if there's bird crap there...I walk around it.
Certainly most inconvenient...hope you can get it out of your clothes!
