This is bollocks!
*Dons JY mask*
We share a back garden and it’s the neighbours boyfriend to be precise
So inferred then that the B/F doesn’t live there, otherwise he would be a neighbour.
we even share a shed with all of our bikes in
So the lady neighbour has lots of bikes? Not unheard of, but fairly co-incidental.
The is/was a strong feeling of trust between us.
That has troll written all over it!
Considering the back door has been open for the last five years this does not wash with me
How does the boyfriend of your neighbour (who doesn’t live there?) know this fact?
Good effort though, especially the prolific references to back doors 😀
