What if I learned Russian in order to curse at my grandparents in a foreign language?
That seems strange. Why would you want to yell at sweet old people!?
I'm not planning to curse at them often, but this way I feel like they don't understand what I'm saying.
I do not care what language you use, you should never curse at your grandparents. It is not okay, they are too sweet to be yelled at!
It's not like I just yelled at them, there are special moments where I just want to say something stronger to show how I feel. I don't even need to do this that often.
I can understand wanting to be able to express yourself even when you are upset and those words might make it easier to let people really know how you feel. But your grandparents deserve more consideration and kindness. They might feel hurt to hear those words from their grandchild.
