Saying "I'm Sorry"

...is something I do too often. Of course, let me clarify.
It's not that I intend to go around offending people. I absolutely hate coming across rudely to others. On top of that, of course, is what the New Testament states about offense. It's basically (my paraphrase) that if you do something that will cause your brother (mainly a Christian who is younger than you) to stumble (sin), then YOU yourself are in sin. But mainly I just really hate the idea of offending or generally causing grief to someone else.
But I can't go around all the time apologizing. It's ridiculous. For example, when I'm in the computer center, and all the computers are completely full, why should I feel so bad about having to inform a patron that there is no room for them? It's no one's fault, but I guess if you had to blame someone, it would be that patron's fault because they neither made an appointment nor came at a time when there was an open computer. I need to stop being so timid when it comes to stuff like that. Being a naturally quiet person is very different from being a meek little mouse who refuses to stand up for herself.
So that's my thought for the day. Ttyl! God bless!
