Thunk! Thunk! Fwap! Thun-thunk! Swap!

The sounds could be herd through most of the top floor.

Thun-thunk! Swap! Fwut! Fwut! Thunk!

There was also the sound of voices, trash talking and grunting, even the occasional laugh.

Fwut! Fwut! Fwut! Thun-thunk! Thunk! BAM!

It sounded almost like a battle to the death, no one outside of the building would relised the sounds were actually coming from two people that were best friends.

Elizabeth grace stark was half knelt on the padded gym floor her knuckles wrapped in combat boxing gloves with enough padding over the knuckles to ensure she didn't injure her younger brother the few times he fought with her.

Across from her almost bouncing on the balls of his feet was American heart throb only recently thawed Steven rogers, he was grinning and his hair was damp with sweat making it even spikier than normal, the grin on his face could make any woman girl of baby instantly swoon and fall in love with him.

Most men to if one was being honest.

But she had built up immunity to the smile ever since she met him at least outwardly, inward she was all kinds of gooey, she'd been nursing a crush on captain ice britches for years.

She rose smoothly to her feet and swatted sweat and strands of hair off her forehead

"What's wrong old woman? Are you getting tired because I could do this all day" she let out a bark of laughter at the man lunging in and trying for a cheap shot he easily blocked

"You're the last person to be calling anyone old grandpa" she mocked blocking his next two hitting before returning with a wide swing of her own.

He raised his arm and tucked his ear into his shoulder protecting his head, the coiled steel that was his muscles easily deflecting her hit and he came at her with to jabs she held her arms to shield her face muscles as strong as iron absorbing the blows with nary a flinch.

When they fought it was like a dance, and it took them all across the room not just in one place.

Their moved were fluid and smooth; planning out their next hit even before their first had landed, trying to stay three moves ahead of each other.

But more than anything it was always fun.

It normally ended with one of them pinned to the floor calling uncle or when someone came to announce that breakfast or lunch was finished, depending on what time Steve had woken that morning and come to use the towers gym.

This time it was both, she called uncle when he managed to knock her to the ground, claiming she was too weak to continue and was withering from lack of food.

Seeing as how only a few short months ago she had been starving it was impressive she could joke about it, but she was a stark, they weren't known for being pansy's, they use to be known for weapons now they were known for being part of the avengers.

Namely the benefactors and the ones that gave everyone, accept for Steve, free room and board.

Temporarily skipping on the showers they went to the main level of the tower wear the kitchen was, Natasha and Clint were gone on a mission wouldn't be back until late that night, tony was more than likely still asleep and Bruce sat in the living room reading a book.

He glanced back when they called out greetings eyes skirting over them and returned to greeting before returning to his book.

It wasn't a surprise he didn't comment on their workout gear, Steve in a pair of loose fitting pants and grey under armor with small shields logos on the shoulder and her in a pit of black compression shorts under red and black gym shorts along with a grey tank top that use to be black.

Sweeping more strands of hair out of her face she reached in the fridge and pulled out a couple of water bottles throwing one at Steve as she opened and drank from the other before she started to make some breakfast, this time omelets with cheese tomato and ham.

"So what are your plans today Stevie wonder?" she asked glancing back she saw the way his brow quirked in confusion at the name and added introduction to Stevie wonder music on the mental list she was keeping for things to bring the man up to speed on the 21st century.

She really needed to write it all down soon lest she forget something vital.

She also saw him shake his head from the corner of her eye "nothing special" she turned and stared at him he looked back brows risen "what?" he asked she rubbed her forehead as she leaned against the counter.

"It's your birthday, and you don't have any plans, none, whatsoever?"

He made a rather unintelligent 'uhh' sound glancing to the side "stay at home and watch TV?" she sighed and raked hair back toured her pony tail "you are hopeless" but she was smiling as she said it so he didn't take offence.

Instead he pointed at the stove "food" she turned "shit!" she quickly turned over the omelet "language" he reminded her and she rolled her eyes.

Silence rained until she sat at the island with their breakfast 10 minutes later "so you're seriously not going to do anything tonight? Not even watch the fireworks? By the way do you have any idea how ironic it is that your birthday is the 4th of July?"

He rolled his eyes "so I've heard, I don't know, maybe I'll go to the roof watch my neighbors set them off for little while" suddenly she smirked "while I try to keep my brother from flying drunk and getting hit by fireworks"

Steve shifted a little looking at her "I since an 'again' in that sentence" she nodded with a sigh "maybe I should just lock down the lab this year" Steve laughed "I don't know if even that would work"

She made a face at him "let a girl dream" she pouted and herd him snort before he patted her head messing up her hair and making her squawk and smack at his hand.

Just another day in the neighborhood.
