Obligation?

I feel kinda obliged to write in this updating whats going down:

• the whole thing is now paid for and expected to be in Costa Rica by May 17.
• I expect Ill be spending all of the little amount of money I have
• Rain, rain, rain and more rain is expected so I am stocking up on rain clothes and light shirts

Thats all I can think of right now, I'm sure I wont check this again until we are in Costa Rica and are expected to update it regularly then

A parting note, a new question I have is what does a fish think in its supposed short memory span?
