I've sent Fang Fang around 201314 text messages in almost 5 years. Why can't she make sense of what I mean?
``But Jesus is here!" the priest intoned. ``Show me your messages."
Fine, the first message is $s_1=``\texttt{c}"$ and the second one is $s_2=``\texttt{ff}"$.
The $i$-th message is $s_i = s_{i-2} + s_{i-1}$ afterwards. Let me give you some examples.
$s_3 = ``\texttt{cff}"$, $s_4 = ``\texttt{ffcff}"$ and $s_5 = ``\texttt{cffffcff}"$.
``I found the $i$-th message's utterly charming," Jesus said.
``Look at the fifth message". $s_5 = ``\texttt{cffffcff}"$ and two $``\texttt{cff}"$ appear in it.
The distance between the first $``\texttt{cff}"$ and the second one we said, is $5$.
``You are right, my friend," Jesus said. ``Love is patient, love is kind.
It does not envy, it does not boast, it is not proud. It does not dishonor others, it is not self-seeking, it is not easily angered, it keeps no record of wrongs.
Love does not delight in evil but rejoices with the truth.
It always protects, always trusts, always hopes, always perseveres."
Listen - look at him in the eye. I will find you, and count the sum of distance between each two different $``\texttt{cff}"$ as substrings of the message.
