So my Grandma was right all the way

"Girls should NOT speak loudly" rebuked my grandma every time I started a conversation. I accused her of being very partial and unfair. She shook her head wisely and said "Your voice is bound to shoot up by several decibels once you have a baby, so practise speaking softly" she declared emphatically.

Maybe grandma is right is what I thought when I, along with another friend went to meet H.
////Now, permit a little digression, dear reader-
H is a friend from college. She is one of those soft natured and gentle girls, whom one could turn to when in need. Only, one needs to have a really sharp ear, when on a phone conversation with her. "The handset wouldn't complain of aches and pains if you be a bit louder" we all used to tell her. But on or off the phone, hardly audible she remained.////
So, few years later, when we went to meet her, we had forgotten the block number of her aptmt. There were 4 blocks, all similar. Just as we were about to call her mobile, there came a deafening THUD. Followed by a loud, angry voice asking the child to behave and giving a huge explanation about how expensive things are. Though dumbstruck, we instantly recognised the voice, followed it and knocked at H's door.

Cut to present. This morning I stepped into the elevator with my little one gaily smiling at the only other person in the lift, and trying to reach for the elevator buttons from his buggy. I was using the oft-repeated, famous-word-of-late "NO" to him. And we got out on our floor. Few minutes later, I heard a knock on the door. It was none other than the man on the lift, flaunting a little shoe which I've seen not rarely. "Guess he kicked his shoe off!" he said, and much to my displeasure, added "I knew you got down this floor, so I came back down, and heard you the minute I stepped out of the lift and followed your voice."

Ofcourse I was not flattered. My flat is the farthest one from the lift. Tips for speaking softly, please!
