I rarely see my assailants as they disappear into the dusk, leaving no trace aside from the beginnings of a bump.
My attackers are, of course, those swarming suckers of summertime: mosquitoes. And there are plenty around at the moment, thanks to all this rain we've had.
Despite making every effort to avoid being bitten in the first place, especially as some mosquitoes carry potentially nasty diseases, the wily little things occasionally slip past my defences.
