First, let me congratulate you and your Delta Pi sisters! When do you have your ritual? I am so excited for you gals!!!!
Second, I say let bowling be bowling/fun/get-to-know-each-other time and have info night during your "Strawberry Bash" (btw, love the name!
) My chapter (Gamma Mu) holds a meeting once a month, and then we also have a social event once a month, where no formal meeting stuff is discussed, we just get together to have a good time. We have social time at the meeting too, but I think that social events should be purely social events.
My third (and final) note,
I LOVE Beta Sigma Phi!
