More than anything else, we just want you to come celebrate with us! That’s the best gift you can possibly give.
If you want to give us something, consider giving your time and helping with party prep. Contact one of us if this is something you wish to do.
Seriously, hold off on the material goods—we are probably moving within the year. If you must give a physical object, make it something we can use up (e.g. eat or drink) before 2014, or something small.
