3 Preflop Folds w/QQ or KK-please chime in

[FoxwoodsFiend]

All these hands are 10/20 NL

Hand 1: hero has KK on button. Villain has 2K I cover (24/4/2 over 440 hands) raises to 85, hero raises to 300, villain raises to 1000, hero folds.

Hand 2: hero (2k)has QQ in BB. UTG raises to 75, UTG+1 calls, villain (same villain from last hand, still covers) raises to 400, folded to hero who folds.

Hand 3: hero has QQ in CO. Different villain with 1K minraises UTG, hero raises to 150, villain raises to 400, hero folds.

Are any of these foolds hard? I didn't think so but anytime I dump QQ/KK twice in one session I worry I'm getting to be too paranoid.
