Hello! Can anyone tell me how to use the verbs <i>pop in/round/over etc/drop in/by/round</i> in the following cases?<br/><br/>-I popped in home.<br/><br/>-I dropped round at Cora's yesterday.<br/><br/>-I popped down to (?) that shop the other day and there wasn't anything interesting there.<br/><br/>Thank you!
