Hey, guys, I'm now doing my homework but I'm not sure about this example:<br/><br/>A: Sorry I'm late!<br/>B:That's all right. <span style="color:#ff0000;">I haven't waited/I haven't been waiting <span style="color:#000000;">long.<br/></span></span><br/><br/>Which one do I have to use? Another example:<br/><br/>She's just got her driving licence. She <span style="color:#ff0000;">hasn't been driving/hasn't driven <span style="color:#000000;">for very long.</span></span><br/><br/>Which one do I have to use, the Present Perfect or the Present Perfect Continuous?<br/><br/>Thank you very much!
