Reading comprehension #49

Dear Patty,
You are invited to a going-away party for Liza, which will hopefully be a surprise.
In honor of her becoming an "Army Wife", we thought it might be funny (and appropriate) to get her a nice set of luggage as a gift. We are asking that everyone chip in $20 to make this a reality. Please let me know if this works for you too.
The party is planned for Liza's last day, which is Friday, June 15th, after work in the break room.
