phone calls and iced tea

i am really, really tired, even though i think i slept enough. i bought an arizona iced tea, maybe if i drink it quickly, it will help wake me up.
anyway. i apparantly missed a phone call last night- 2, actually. i must have been in the kitchen when they were made because i never heard my phone ring. this morning, i saw that there was a voicemail, and figured it was cvs calling to remind me about one of my many prescriptions. so i ignored it until i got down to to open the shop.
they were from my youngest brother.
the one i've spoken to only once in 7 years.
and now i'm worried about it-
why was he calling? i called him two weeks ago to wish him a happy anniversary, (he got married a few weeks before me, last year.) is that why?
is it something to do with the woman who gave birth to me, the one i haven't spoken to in 10 years? i hope not.
he did say that he wanted to wish me a happy anniversary...(steve and will be having our one-year wedding anniversary on august 31st.) but he also asked me to call back.

i hope that the worry and fear in my mind are unfounded.
