I know that sometimes we might want to share about other things that are not really on topic with Christianity, like talking about secular games, movies or music, but please try to share those secular topics that have some type of Christian faith message in them.
Kinda like the movie "Where Hope Grows", which both the Misses and I loved very much! The lead actors character has a bad drinking problem and anger issues, but it all turns to a positive message in the end.
Anyway I hope that that all makes sense.
Now go have fun!
