Because of that 'pitch definition' was lacking.  Seems fast is ok...
"Trust me..."  Following a load of nothing but highly perfumed manure masquerading as perceptive, personal insights.

"You'll thank me..." Following another load of manure dressed up as an authoritative statement negating any contrary facts or opinions.
