Here are some text conversations between adult Mycroft and Sherlock, all short and written as soon as they popped into my head. Please review! T for some mild swearing.
Sherlock?
Mycroft. How's your head cold? SH
Wrong, brother mine. Again.
Shut up. SH
Yet another piece of proof that I am the smart one. Think, Sherlock, it shouldn't be too much of a challenge for you. There are infinite reasons why I might not be able to talk, I might be suffering from an asthma attack, be in a church or other place of worship, just have had by tongue burned, cut or stung by an insect…
Why am I needed? SH
Nice change of subject…I merely wanted to wish you birthday greetings.
I hate birthdays. So boring. SH
I know.
Of course you would. SH
That was 30 years ago, Sherlock.
You still owe me for that little incident. SH
Oh, grow up!
