For me it's the lawn-cutting/snow-shovelling/leaf-raking.
Get a tenant in.
My landlady lives two floors below me, on the ground floor. From March to December, I never see her. However, as soon as the serious snow comes, she's hovering around the main door, shovel in hand and downtrodden expression on face, as soon as I put the key in the lock.
And then she sighs and says something like, "Oh well, Herr treibeis, at least it means I don't have to pay all that money to go to a fitness studio". And then, staring wistfully at the ever-increasing drifts outside, she groans, grasps the small of her back, winces, whimpers, affects a limp and and goes as if to set to work.
It would take a harder man than me to not wrestle the shovel from her grasp and spend an hour doing her job for her.
And what do I get I return? A bottle of low-alcohol Jever that's a year and a half past its sell-by date.
