Friend of Foe, Dropping Presents

I myself have accidentally dropped presents that ended up hidden somewhere in a neighbours landing zone (that's where I've been dropping most, if not all, presents). The few times it has happened have always been accidental - as said above, they don't always go where intended. In all but one case I have been able to pm the neighbour to tell them where the gift is - but I'm fairly certain a couple of them have not checked their pm's.

I'm certainly hoping no one holds it against me - again, it wasn't intentional.
