Sonoma weather February 3rd

You must be his X-Wife.

Nancy!!

Be nice now Nancy. Simmer down.

Really??? "Big outdoor party

I think this is a perfect way to get through a divorce. What fun.

BIG OUTDOOR DIVORCE PARTY

Now, what in the world is pathetic about having a big outdoor party after a divorce?! I would like to know because each and every year since 1990, I celebrate "my" Divorce Day! I cannot see myself mourning over a marriage we both found out was not meant to be. Therefore, hibernating in my room drenched in tears is not going to happen. Note that you posted a hater comment, and hater comments are only made by someone feeling envy for something they wish they were bold enough to do their very own self... (It's ok, we understand.)

Wedding in April versus July in Berkeley, CA

Hi,

We are planning a wedding for either April 18th or July 3rd, 2019 in Berkeley, CA. This seems to say that the summer months may be warmer than normal. Do you think it will be too hot in July for our guests who are from Ireland? As you know, many homes and buildings in the Bay Area don't have air conditioning. So we are wondering if we should switch from our July date to April. The wedding is at an outdoor/indoor venue and I'm not sure if the indoor hall has air conditioning.

Thanks for your thoughts,
Brooke
