How do you tell your kids that you are too tired from work and you won't be able to play or attend to them as you need to rest first?

For my experience, kapag umuuwi ako ng late or pagod man, bumibili ako ng pasalubong para dun mafocus ang attention ng kids sa paguwi ko. Then after na nkapgrest ako ng saglit dun na lang ako makikipag play sakanila.
