If you had a freeway billboard, what would it say?

A simple question for day six of Bloganuary, but still one that I had to some thought into.
My girlfriend and I did a bit of over Christmas and New Year, so we saw a few billboards, and noticed some new ones along the way. Those ones mostly advertised businesses our events, it would have been nice to see something different.
For my billboard, I would want it to say ‘You never know what someone is going though, be kind, always.’ I know that sounds corny, but it’s something that people need to be aware of.
This post is short and sweet, I’lol see you tomorrow for day five.
