Two 2/4-hands...am i being weak-tight??

[KSakuraba]

Two hands i really feel i might've messed up, and would appreciate any comments. I hate nothing more than showing this kind of weakness...
Both tables are pretty usual 2/4-tables, tightish players with flops seen-% around 25%-30%. Either one of villains hasn't been involving in pots too much, that's all info i've got.

Hand 1.

Stack's involved: Hero(~900€)
Villain(~300€)

Two limpers to hero in LP who makes it 20 with red KK. Villain calls from utg+1, others fold.

Flop(Pot ~50)
Q/images/graemlins/spade.gif 8/images/graemlins/spade.gif 6/images/graemlins/diamond.gif

Villain bets 30€
hero raises to 80€
Villain raises to 150€, leaving himself with a bit over 100€.

Hero...folds. /images/graemlins/mad.gif



Hand 2.

Stacks involved:
Hero(~450€)
Villain(~400€)

Villain limps from utg+1, all folds to hero in MP who makes it 20 with black TT. Only villain calls.

Flop(Pot ~45);
2/images/graemlins/diamond.gif 6/images/graemlins/heart.gif 7/images/graemlins/club.gif

Villain checks, hero bets 30€, villain calls

Turn (Pot ~105)
2/images/graemlins/spade.gif

Villain checks, hero bets 75€, villain raises to 150€ (Leaves him with ~200€)
Hero uses his time bank and...folds /images/graemlins/mad.gif /images/graemlins/mad.gif

I know there's a decent chance that i was behind in both of those hands but i just really hate folding overpairs. Anything i could've done differently? All comments greatly appreciated.

Thanks, guys.
