Ineffective
What I like less than freezing up because I was rushing, and not thanking someone when they do me a favour (stopping a bus that I was running for), is getting the opportunity to return the favour to someone else later on in the same day, and again freezing up out of just blatant indecisiveness. I don't know why I have to debate helping someone when I get the chance to, but I seem to be afraid of having stuck out my neck when I didn't have to.
