The idea of a lodger seems unfathomable now but used to much more common.
An example from history...
My grandma had a small 3 bedroom terraced cottage and 3 DC. DH passed away young so she was a single Mum, no welfare, had to work several jobs, repair clothes, do all the heavy work, which housework really was and so much more.
Only option was to take in lodgers for extra income so took in 2 or 3 at any given time. DC had one bed in one room to sleep together, which she would also use if 3 lodgers with 2 sharing.
She got up early hours to set the coal fire, make a cooked breakfast for them, walked kids to school, went to work, came home and cooked evening meal for them, then back out to work, repeat...
It was so tough then, huge admiration for that generation, true graft, resilient, harsh.
We've all become much more comfortable, even if struggling, there is help with benefits etc, so the idea of taking in a lodger makes us gasp.
We're fortunate times have changed. Xx
