I loved my ex-"son-in-law". His pot habit caused him to push my daughter into asking him to leave her and their son's life. And it broke her heart to do it, she really didn't have any other choice.
Her life and my grandson's turned around beautifully, his didn't as he is still doing the same things.
I know some recreational smokers. And some social drinkers. And people who always speed on the freeway...and I get mad at them because I don't want them to cause me to get in an accident! Just like I don't want someone else's smoking getting me in trouble.
