Elena's Tuesday ends with a question she can't answer.
Three sessions on Tuesday. The Morrison family paid monthly in advance. The Patels pay per session. The grandmother of one student sends e-transfers from an account Elena has never seen before.
At 8pm a parent texts: did we pay for last week? Elena opens her banking app. She isn't sure either.
She is a good tutor. She prepares for every session and remembers which kid struggles with fractions. The payment part just lives in too many places.
