I got a GTalk chat request from someone random yesterday (actually random, in that I have no idea who they were). I answered it:
1:42 PM adumasarts: hola preciosa
1:43 PM me: not sure I'm who you think I am
1:44 PM adumasarts: when are you
me: now
adumasarts: yes
me: OK.
adumasarts: hello!
Made me laugh.
