@DaleOh Nonono, it is important.
When my former daughter became my son, I felt I had little choice but to act like a true dad (with dad jokes) and, therefore, instantly declared that from now on, I (literally) no longer had a daughter.
Yes, that is how I reacted when my son came out of the closet. It is not difficult if you want your kids to be happy.
Besides, he always loved my "dad jokes." His reply was somewhat: "NO, but, also YES, and, aargh! ... DAD!"
@DaleOh "What's next? Transspecies?? RIDICULOUS!"
