My friends Joanna is worried that thieves might target her house while she is on holiday. However, we are going to keep an eye on her house for her.
Explanation:
Thief- the plural form for thief is thieves.
However- The H needs in however should be capatilized since it's the beggining of the sentance.
Are- The subject and verb in the sentence do not agree. If your subject is plural (we), then your verb also has to be plural (are). Using (is) after (we) would be incorrect.
