Procurement, Logistics, and ContractsEnron Broadband Services, Inc.1400 Smith, Suite EB-4573AHouston, TX 77002The week is going OK. All the tennis and swimming has left me with sore muscles so this is my night off. Am planning to do some more house chores so I do not end up with another weekend like the last.

I'm still planning on coming to Austin next weekend, I'm just not sure when, but I'll let you know.

Call if you get lonely!

Love,Sooz

Procurement, Logistics, and ContractsEnron Broadband Services, Inc.1400 Smith, Suite EB-4573AHouston, TX 77002Had another sleepless night Sun. and finally took some Unisom and had a good night's sleep last night. What a relief. I have really never had this problem before. It's good to have a lot of energy, but you have to shut down sometime.

Am sending you my travel schedule for next week. The following week (May 29 - June 2) I'm planning to be in SF also, but I'm not sure I'll actually have to be there that long.

Have a good afternoon!
