Mister Bojler and the Pool Plans

So one day me and about 3 friends went out, and we made plans that we should go

to the pool the next day in the morning. Everything was going well,

we all agreed that were gonna go. And suddenly, boom. One of our friends's

water heater broke and he had to call the majstor(construction worker) to fix it. So he cancelled

the plans and was like "guys my water heater is broken i cant make this shit up i gotta

call the majstor to fix it". And we just thought it was a stupid reason to back out

and not come. After that it became an inside joke that he’s mister bojler (water heater in

our language); what do you guys think?
