How about because you think you look wrong when you're late? Or it makes you stand out if you walk in late, or people might not think you have it all together, they might judge you?
Could be bug. Esp. the not have it all together part. I purposely slowed my pace this morning going to church and showed up about 10 min late (I know right?!?!). Weird thing happened, no one said what your late!!! Matter of fact they barely noticed, they just fell into conversation with me (I did not apologize for being late either). I'm such a rebel lol.
You can not change your past, but you can ruin a perfectly good present by worrying about the future.
