Hehe... I never loose on purpose.. to anyone.. Not my wife, not my kids, not brother, not my sisters... Nowadays I mostly play with my kids, I might give my 3 year old some slack, but my 7 year old? nah, she better get gud or get goin....
Seriously though... If we play non video games, then I let them win all the time... Cardgames, boardgames or just generally messing around... But videogames are a rite of passage... If you want to play with daddy's ps4 or switch, you gotta prove you can hang with the big boys....!
