can i come over?

you: hey can i come over?
friend: um... why?
you: ....ohhh okay, um, i'll just call back in 10 min.

so lisa and i have decided that:

if you call someone and ask to come over and they respond with "why?" it's an automatic assumption that they are doing the nasty with or without a partner. the correct response would be to let them know you'll call back in a varying amount of time (as little as 1min--depending on the person, make your best judgment).

with this tactic, you should be able to avoid any embarrassment or awkwardness you or the receiver may experience if the conversation leads elsewhere.
