Send someone a real letter

Well today I wrote someone I haven't seen in more than 17 years.
I just found out this person was coming home and I wanted to give him advice on things he should be doing to prepare for society and moving forward in a positive direction. I also stressed that life is different and he needs to jump right into getting started with his second chance and I sent him some vocabulary words to get used to using again instead of the slang he uses. Hopefully he will take my advice but either way he has my prayers.
