Is my neighbour a drug dealer?

[bednobs]

so i've been at home now for nearly 5 months. During the day on almost EVERY weekday, the neighbour over the road has a dpd van pull up to their house, stay about 5 minutes then leave they live down a little alley, so i can't see what they do :) (damn!)
me and mr bed have been trying to work out why you would have a delivery van arrive EVERY day (different drivers, so not an affair)
What do you reckon, drug deliveries?

Drug dealers or an international terrorist cell, I'd say. Although the truth is that they are probably just home workers, but that's not nearly so interesting.

Could you maybe go undercover as a Jehovah's Wintess and call round on them?
