You might have great intentions to help someone, but until you do it, it does not mean much. Be careful what you say to others. If you make it sound to them like you are trying to make an effort on their behalf or if you never offer to help or don't respond, that is one thing. If you do offer to help and don't, potential friends will be disappointed.
So in this time of year try to make a new friend. It might even bring you new happiness! Happy Valentine's Day!
