l-i-t-t-e-r spells bin

whilst stuck on a train today (usual journey time 5 mins, today 30 mins) esther and i did some spelling practice.
i saw a sign saying ‘litter’ by a bin. i went through the word phonetically –
“li spells ‘li’
double tt is ‘t’
er is like at the end of esther, so is ‘er’
li – tt – er , li-tt-er. what does that spell ?”
“it spells bin” said esther.
“don’t be a fool” i said. “it spells ‘litter'”.
“what’s litter daddy” said esther.
and therein lies the problem. kids today read everywhere “do not drop litter” yet they don’t even know what litter is.
