gate-crashers

Everything was fine when I left for work yesterday morning. When I came home, dozens of ants greeted me in the kitchen, industriously scurrying back and forth between sink and window. I have no idea where they come from and whether they intend to settle here for good, inviting other members of their extended family to abuse my hospitality, I just hope they like potion in the ant trap I bought this morning. Adios amigos, don't outstay your welcome...
