faithful: Recently, a friend of mine who works for me was offered another job.  He is so vital to our team in our business.  I really did not want him to leave the company.  In the end, he was faithful to our company.  I am thankful for such a good friend.

A friend of mine who works for me (really with me) was recently offered another job for a little more pay.  I was quite nervous on what he would decide.  In fact, he never even mentioned it to me.  I found out through an acquaintance that he had been offered the job.

I hope you don't feel jealous of your friend. Did he accept the job?

It wasn't so much jealousy.  I just depend on him a lot.  What was funny was that I asked him about it, and he told me, "I never mentioned it because I never considered it.  We've got too good a thing going here."  I was amazed at his loyalty.

Seems like you have a trustworthy friend for life! I hope you cherish this friendship.

I most certainly do.  He really is a good friend.  I won't forget that.  I just hope I become as good a friend to him as he has been to me.
