I have a few superstitions. One is knocking on wood. The other is that I won't divulge what I think is pending good news before it is confirmed. Example ... a job interview that went really well - I won't tell anyone until an offer is made (and accepted) because I always think the moment I say "I might get ....." my karma will change.
Ladders, mirrors, black cats, cracks on sidewalks, and spilt milk or salt ... no superstitions.
And ALL my dogs have multiple names that develop over the years. With some, the original name was eventually lost.
