I'm not as young as I used to be.

My 25th birthday is Friday, and my husband and I are throwing me a birthday party.

I haven't had one of those is nine years; for my 16th, I invited all my friends over and we had a very mundane sleepover in my much-too-small bedroom. I think we were all asleep by 11, thanks to my mom ushering us upstairs so we wouldn't keep my kid sister awake. I remember singing Limp Bizkit's "Faith" very obnoxiously.

Good times.

Today, though, I realized that I'm not as young as I used to be. Unfortunately this realization came with the onset of a massive sinus headache that slammed into my face at 4PM. A 45 minute visit to the post office didn't help. I normally love the post office - I love any kind of predictable bureaucracy. Today, though...multiple people in front of me with multiple heavy packages headed to Mexico; an annoying man with an eBay business; and a maid-of-honor with her friend's wedding invitations arguing over postage (heaven forbid you have TWO stamps on the envelopes!).

I don't know what annoyed me more, though - the people who did nothing wrong other than be in front of me in line, or the headache that was clawing at my skull. Either way, it made me feel old.

I skipped class. I laid around on the couch and enjoyed being with my husband instead.

Maybe being old ain't so bad.
