the awkward silence

dont you hate it when that happens!! there is a girl in my year who ive been good friends with since infant school but lately we havent really been chatting much, since highschool we have hang around with different friendship groups and we used to chill out on weekends or after school. but lately we havent really spoke much. its weird....i guess its cos neither of us have made the effort, we are working together in our drama gcse exam but when we arent doing that we arent really chatting except the odd hello here and there if we see each other. shes changed big time as have i. but its so awkward when we have the silence!!! lol.
